FEATURES - Utilizes minimum area where printed wiring board space is most important - Wound from PETP polyester film and thin gauge Ro HS foil under carefully controlled atmospheric PLIANT conditions - Protected against moisture by a conformal coating of epoxy - Specifically designed for printed wiring board applications - Widely used in puters, instrumentation and telemunications equipment - 100 VDC through 600 VDC, may be operated up to + 125 °C with proper dearting PERFORMANCE CHARACTERISTICS Operating Temperature: - 55 °C to + 85 °C To + 105 °C when working voltage is reduced to 70 % of + 85 °C rating; to + 125 °C when working voltage is reduced to 50 % of 85 °C rating Dielectric Withstanding Voltage: Capacitors shall withstand a DC potential of 250 % of rated voltage applied between terminals for not more than 5 seconds. The test voltage must be applied and discharged through a resistor of 1 ohm per volt. Insulation Resistance: After a 2 minute charge at rated Humidity Test: voltage or 500 V, whichever is less. Condition capacitors with no voltage applied for 72 hours at At + 25 °C: 100 000 Megohm for C ≤ 0.25 Microfarads 95 % relative humidity and + 75 °C. Remove capacitors from 25000 Megohm - Microfarads for C > 0.25 Microfarads humidity chamber, wipe surface dry of moisture and dry in At + 85 °C: 10 000 Megohm for C ≤ 0.15 Microfarads circulating air for 4 hours. Measure insulation resistance after 1500 Megohm - Microfarads for C > 0.15 Microfarads .. a 2 minute charge at 25 °C and rated voltage or 500 VDC, At + 105 °C: 1500 Megohm for C ≤ 0.17 Microfarads whichever is less. Minimum product of insulation resistance 250 Megohm - Microfarads for C > 0.17 Microfarads and capacitance shall be 5000 Megohm - Microfarads after At + 125 °C: 200 Megohm for C ≤ 0.13 Microfarads test but need not exceed 10 000 Megohm. Not more than 25 Megohm - Microfarads for C > 0.13 Microfarads one failure allowed in 12 units tested. Capacitance Tolerance and Dissipation Factor: DC...
