Notes: All dimensions are typical in inches (mm) Tolerance: Inches x.xx = ±0.01 Millimeters x.x = ±0.25 x.xx = ±0.13 Pin 1 is marked by a “dot” or indentation on the unit. The curved edge of the case indicates the Pin 1 side. Model Selection Guide Mechanical Dimensions Notes: 1. Load regulation is measured for an output change of 20% to 100%. 2. When measuring output ripple, it is recommended that an external 0.33 µF ceramic capacitor be placed from the +Vout pin to the -Vout pin. For noise sensitive applications, the use of 0.47 µF capacitors will reduce the output ripple. 3. Operation at no-load will not damage these units. However, they may not meet all specifi cations. 4. The converter should be connected to a low ac-impedance source. An input source with a highly inductive impedance may affect the stability of the converter. In applications where the converter output loading is high and input power is sup- plied over long lines, it may be necessary to use a capacitor on the input to insure start-up. In this case, it is recommended that a low ESR (ESR <1.0 Ω at 100 kHz) capacitor be mounted close to the converter. For 5V input units a 2.2 µF is recommended, for 12V input units, a 1.0 µF, and for 24V input units, a 0.47 µF. 5. It is recommended that a fuse be used on the input of a power supply for protection. See the table above for the correct rating.
