Type 418P
Vishay Sprague

Polyester Capacitors Filmite "E", ORANGE DROP , Radial Lead
FEATURES
Identical performance characteristics to Type 225P pressed polyester capacitors through 600 WVDC ratings RoHS Wound from PETP polyester film and thin gauge COMPLIANT foil under carefully controlled atmospheric conditions Protected against moisture by a conformal coating of epoxy Specifically designed for printed wiring board applications Widely used in computers, instrumentation and telecommunications equipment

PERFORMANCE CHARACTERISTICS
Operating Temperature: - 55 C to + 85 C, standard; up to + 105 C when WVDC is reduced to 70 % of + 85 C rating. To + 125 C when WVDC is 50 % of + 85 C rating. Insulation Resistance: After a 2 minute charge at rated voltage or 500 V, whichever is less. At + 25 C: 100 000 Megohm for C 0.25 Microfarads 25000 Megohm - Microfarads for C > 0.25 Microfarads At + 85 C: 10 000 Megohm for C 0.15 Microfarads 1500 Megohm - Microfarads for C > 0.15 Microfarads At + 105 C: 1500 Megohm for C 0.17 Microfarads 250 Megohm - Microfarads for C > 0.17 Microfarads At + 125 C: 200 Megohm for C 0.13 Microfarads 25 Megohm - Microfarads for C > 0.13 Microfarads Capacitance Tolerance and Dissipation Factor: Capacitors shall be measured at a frequency for 1000 Hz at + 25 C or else be referred to measurements made at that frequency and temperature. The maximum dissipation factor shall be 0.75 %. Dielectric Withstanding Voltage: Capacitors rated below 1000 volts shall withstand a DC potential of 250 % of rated voltage appl
ied between terminals for not more than 5 seconds. Capacitance rated 1000 volts and above shall withstand a DC potential of 200 % of rated voltage applied between the terminals for not more than 5 seconds. The test voltage must be applied and discharged through a resistor of 1 ohm per volt. Humidity Test: Condition capacitors with no voltage applied for 72 hours at 95 % relative humidity and + 75 C. Remove capacitors from humidity chamber, wipe surface dry of moisture and dry in circulating air for 4 hours. Measure insulation resistance after a 2 minute charge at 25 C and rated voltage or 500 VDC, whichever is less. Minimum product of insulation resistance and capacitance shall be 5000 Megohm - Microfarads after test but need not exceed 10 000 Megohm. Not more than one failure allowed in 12 units tested. DC Life Test: Capacitance are capable of withstanding a 500 hour life test at + 85 C at 150 % of rated working voltage. After test, capacitance shall not have changed by more than 5 % of initial value, in
sulation resistance shall not have decreased by more than 50 % of the initial limit and dissipation factor shall not have increased to more than 1 %.
