INSTRUCTIONS OF CAPACITORS CAUTIONS ON USE OF CAPACITOR 1. POLARITY - Solid electrolytic capacitors are polarized capacitors. Use capacitors after verifying their positive and negative polarities. If these capacitors are installed in the reverse polarity, its life may shorten because of increasing leakage current or short circuit. 2. Types of circuits in which capacitors are prohibited from being used PEV5 series may be heated by soldering to increase in its leakage current slightly. This may have some influence on the characteristics capacitors in the following circuits. (1) Time constant circuit (2) Coupling circuit DIM Value TW 16.0±0.3mm CL 7.0±0.2mm CW 7.0±0.2mm CH 7.5±0.1mm HE 1.75±0.1mm CP 12.0±0.1mm TT 6.3±0.2mm FT 0.4±0.1mm ΦHD 1.5 +0.1 -0.0 mm CC 2.0±0.1mm HP 4.0±0.1mm DIM Value ΦRD 381.0±2mm AD 100±0.5mm ΦHD 13.0±0.5mm RW 16.5±0.8mm End Start 400mm Min 100mm Min160mm Min LeaderNo ComponentsNo Components Components Direction of feed

OVER VOLTAGE - If PEV5 series is applied a voltage higher than the rated voltage for an instantaneous period, it may be defected due to short circuit.Note that the voltage over the rated voltage must not be applied to capacitors. 4. REPEAT OF RAPID CHARGING AND DISCHARGING - If PEV5 series is used in a rapid charging and discharging circuit or receive the flow of excess rush current, its life may shorten by large leakage current or short circuit.The charging and discharging current through PEV5 series should be less than 10A. 5. REFLOW SOLDERING - High soldering temperature and long soldering time will affect the characteristics of the capacitors. Use reflow soldering condition within the recommended range. Also, the temperature varies with the location and population of the components, the material and the thickness of printed circuit board. Verify temperature profiles prior to actual production run. 6. USE OF CAPACITORS FOR INDUSTRIAL EQUIPMENT - When capacitors are used for industrial equipment, the circuits should be designed to have sufficient margins in the ratings of capacitors including capacitance and impedance. Without sufficient margins in the characteristics, the reliability of the capacitors may be reduced by their shorter life. Always contact us if you want to use capacitors for equipment affecting human lives such as space, aviation, atomic power, and medical devices. Never use capacitors for the used without our prior approval. NOTES ON CIRCUIT DESIGNS FOR CAPACITORS 1. RATING AND PERFORMANCE - Use capacitors within the rating and performance ranges defined in the brochures and delivery specification of capacitors after checking the operating and installation environments. 2. OPERATING TEMPERATURE - If PEV5 series is used at a temperature higher than the upper specified temperature (105ºC), its life may be remarkably shortened or the leakage current may increase to cause defective. 3. RIPPLE CURRENT - Never make current larger than the rated ripple current through PEV5 series. If excess ripple current flows through PEV5 series, internal heat may be generated largely to make its life shortened or cause it to be defected due to short circuit 4. LEAKAGE CURRENT - Depending on the reflow soldering conditions, the leakage current of PEV5 series may increase slightly. The application of DC voltage enables the capacitors to be repaired by itself. This leads the leakage current to be smaller gradually. The leakage current can be reduced fast if the DC voltage, which is less than the rating voltage, is applied at the temperature close to the upper specified temperature. 5. APPLIED VOLTAGE - Do not apply voltages exceeding the full rated voltage. If such voltage is applied, it may cause short circuit even though it is just a moment. (1) Sum of DC voltage and the peak of ripple voltage AC voltage shall not exceed the rated voltage or category voltage. (2) The sum of the DC voltage plus the negative peak AC voltage shall not allow reverse voltage. (3) Do not apply reverse voltage. (4) For 25V products, the applied voltage shall follow the following figure as the temperature is higher than 85℃。 6. FAILURE MODE - PEV5 series contains a conductive polymer as material of cathode electrode. Therefore, like other solid electrolyte capacitors, the life ends mostly due to random failure mode, mainly short circuit. If a current continuously flow through the capacitor due to short circuit, the capacitor would be overheated higher than 300ºC and then aluminum case of the capacitor would be removed by increasing internal pressure due to the vaporization of materials. 7. INSULATION - (1) Plastic coated case of capacitors is not secured to insulate. Do not use capacitors in areas requiring insulation. (2) Isolate the case of PEV5 series from the positive and negative terminals and adjacent circuit patterns. 8. DESIGN OF PRINTED CIRCUIT BOARD - Take note on the subjects when capacitors are installed on printed circuit boards: (1) For surface mount capacitors, design the copper pads/lands of a printed circuit board according to the catalog or product specifications. (2) Do not place heating components on boards to be close to capacitors or in the backside of them 9. PARALLEL CONNECTION - If PEV5 series is connected with another type of a capacitor in parallel, larger ripple current may flow through one of capacitors. Take the current balance among them into account in circuit designs. 10. USING TEMPERATURE AND FREQUENCY - The electric characteristics of capacitors depend on the variations of the ambient temperature and frequency. Check the variations in designing circuits. NOTES ON INSTALLATION OF CAPACITORS 1. NOTES ON PRE-INSTALLATION OF CAPACITORS - (1) Do not reuse capacitors installed in a unit with the power supply turned on for another unit. No used capacitors shall be reused excluding those removed to measure their electric characteristics in periodical inspection. (2) If PEV5 series stored for a long period may often increase in its leakage current, connect a resistor of approximately 1kΩ to the capacitors for voltage treatment. 2. NOTES AT INSTALLATION OF CAPACITORS - (1) Install capacitors in a unit after confirming that their ratings (rated capacitance and rated voltages) meet the conditions of the unit. (2) Install capacitors in the correct polarities. (3) Take care not to drop capacitors on floors. Do not use capacitors dropped on floors. (4) Do not deform capacitors to install them in units. (5) Note capacitors may be damaged by mechanical shocks caused by the vacuum head, component checker or centering operation of an automatic mounting machine. (6) Do not dip the body of a capacitor into the solder bath. (7) Do not solder capacitors more than once by reflow. Consult us for reflow-soldering them twice over. (8) Do not apply mechanical stress to the capacitor after soldering to the printed circuit board. (9) Do not use adhesives and coating materials containing halogenated solvents NOTES ON USE OF CAPACITORS IN UNIT (1) Never make your fingers contact with the capacitor terminals.

Conductive Polymer Aluminum Solid Capacitors (V Chip) RoHS MERITEK PEV5 Series (2) Do not make capacitor terminals to be in contact with each other through a conductor. Do not put conductive liquid such as acid and alkali solutions on capacitors. (3) Confirm that the unit including capacitors is placed in proper conditions. Do not place the unit in the following areas: (a) Area in which they are directly exposed to water, brine, or oil or in condensation status. (b) Area filled with poisonous gases including hydrogen sulfide, sulfurous acid, nitrous acid, chlorine and ammonia. (c) Area to which ultraviolet and/or radial rays are radiated (4) Provide aging for a unit containing capacitors within the period defined for them. (5) It is recommended to use a unit containing capacitors in the normal temperature range of 15℃ to 35℃ and the normal humidity range of 75% or less ACTION AT EMERGENCY (1) At the occurrence of short circuit in PEV5 series, some heat is generated from it if the short-current rather small. If the short current exceeds the above value, the capacitors are heated excessively. If so, turn off the power of the unit without your face and hands being close to the capacitors. (2) If you should expose your eyes to smoke from the capacitor or inhale it, immediately flush the open eyes and gargle with water. STORAGE (1) Store capacitors in an area in the temperature range between 15ºC to 35ºC and the relative humidity of 75% or less without direct sunshine. In addition, store them in the package states if possible. (2)SMD products are sealed in a special laminated aluminum bag. Use all capacitors once the bag is opened. Return unused capacitors to the bag, and seal it with a zipper. After the bag is opened, please use all capacitors within 1 month. (3) Store capacitors in an airtight bag to keep the terminals in good condition. (4)Store in a location where the capacitor is not exposed to ozone, ultraviolet radiation, or other radiation. (5)Never store capacitors in any area in which they are directly exposed to water, brine, or oil or in condensation status. EXHAUSTION OF CAPACITORS Capacitors are composed of organic compounds, resins and metals. Request an industrial dispose company to dispose of used Capacitors.
