Rodney French Blvd.•New Bedford, MA 02744•Ph: (508)996-8564•Fax: (508)996-3830• www.cde.com Type CMR , High-Reliability, Mica Capacitors Specifications Capacitance is within tolerance when measured at these frequencies: 1 - 1000 pF @ 1 MHz > 1000 pF @ 1 Khz Dissipation Factor limits are below. Measure dissipation factor at 1 MHz when the capacitance is 1 pF to 1000 pF, and at 1 kHz when the capacitance is greater than 1000 pF. Dissipation factor is equal to DF = 2pfRC, where f is the test frequency, R is the equivalent series resistance, and C is the capaci- tance. For other capacitance values, see Figure 1. Capacitance Dissipation Factor 100-1000 pF 0.00075 max at 1 MHz 1100-3300 pF 0.0014 max at 1 kHz 3600-9100 pF 0.0013 max at 1 kHz 10,000 pF 0.0012 max at 1 kHz Quality Factor (Q) is the reciprocal of dissipation factor. Insulation Resistance for capacitanc- es up to 10,000 pF is greater than 100 G. at 25 ºC, greater then 10 G. at 125 ºC, and greater than 5 G. at 150 ºC. For other capacitance values and tempera- tures, see Figure 2. Withstanding Voltage is two times the rated voltage, and can be applied up to 5 seconds without damage. Temperature Coefficient and Capaci- tance Drift measure the capacitors’ capacitance at 25 ºC, -55 ºC, 25 ºC, 125 ºC (or 150 ºC) and at 25 ºC after stabilizing at each temperature. The capaciance will meet the limits of the Characteristic table shown in Ordering Information. Failure Rate: Type CMR capacitors have specified failure rate levels ranging from 0.01% to 1.0% per 1000 hours. The fail- ure rate level is established at 90% confi- dence level and is referred to operation- al life at full rated voltage at maximum rated temperature. High Voltage Stabilization: We sub - ject capacitors with Failure Levels M, P , and R to a burn-in at twice rated voltage, at rated temperature, for a minimum of 48 hours. Capacitors that show dam- age, arcing, breakdown, or low IR are removed. We reject the lot if more then 8% of the capacitors fail. Solderability: After an 8-hour steam aging, coat leads with a rosin flux (R) and immerse in molten 245 ºC ±5 ºC 60/40 tin/lead solder. Solder coverage will be no less than 95% when examined at 10X magnification. Life Test: Subject the capacitors to maximum operating temperature (+125 ºC or +150 ºC) with 1.5 times rated volt - age applied for 10,000 hours. Take readings and make visual observations every 2000 hours. There will be no visual damage and the capacitors will meet the after-test limits on the following page. Resistance to Solvents: Subject the capacitors to three cycles of 3 minute immersion in solvent, 10 strokes with bristle brush and, where applicable, ½ minute in vapor, per MIL-STD-202, Method 215. Repeat the three cycles for three solvent mixtures: Isolpropyl alchol mixture (Solvent 1), azeotrope mixture (Solvent 3), and water/propylene-glycol mixture (Solvent 4). The marking will not rub off or smear and there will be no visible damage to the capacitor body. Refer to MIL-STD-202 for details. Resistance to Soldering Heat: Capac - itors will meet the requirements of MIL- STD-202, Method 210 Test Condition G. Immerse capacitor leads to within .250 inches (6.4 mm) of the body in molten tin/lead solder (260 ºC ±5 ºC) for 10 ±2 seconds. Allow to cool. Capacitors will meet the after-test limits on the follow - ing page. Marking of capacitors conforms to method I of MIL-STD-1285, and includes the type designation, “JAN, ” brand, trademark, source code, date code, rat - ed voltage, capacitance, capacitance tolerance, and the highest rated tem- perature. Small capacitors are marked with the letter “J” .

Rodney French Blvd.•New Bedford, MA 02744•Ph: (508)996-8564•Fax: (508)996-3830• www.cde.com Moisture Resistance: Capacitors will meet the requirements of MIL-STD-202, Method 106F as outlined here and diagrammed on the right. Apply 100 V or the rated voltage (whichever is less) to half of the capacitors. Don’t apply voltage to the other half. Refer to MIL-STD- 202 for details. 1. Dry capacitors for 24 hours in a 50±2 °C oven and then allow to stabilize at room temperature. 2. Subject the capacitors to 20 24- hour continuous cycles with relative humidity and temperature as shown. 3. 4 to 24 hours after completion of the last cycle the capacitors will show no visual damage and will meet the after-test limits below.
