请问X电容的耐压怎么测??
X电容的规格是这样:
GENERAL TECHNICAL DATA
Dielectric:
Polypropylene film.
Plates:
Meal layer deposited by evaporation under vacuum.
Winding:
Non-inductive type.
Leads:
Tinned wire.
Protection:
Plastic case, epoxy resin filled.
Box materials is solbent resistant and flame retardant according to UL94V-0.
Marking:
Manufacturer’s logo, series, capacitance, tolerance, Related documents: IEC 384-14 2nd Edition 1993
Operating temperature range:
-40 to +100oC
ELECTRICAL CHARACTERISTICS
Rated voltage (Vr):
275Vac; 50/60Hz
Capacitance range:
4700pF to 1.0uF
Capacitance values:
E12 series (IEC 63 Norm).
Capacitance tolerances (measured at 1kHz)
±5%(J);±10%(K);±20%(M)
Dissipation factor(DF):
≤0.1% at 1KHZ/200C
≤0.3% at 10KHZ/20oC
Withstand voltage:
Applied 1,200 Vac for 60 sec or 2,100 Vdc for 1 sec
Insulation resistance:
Test conditions
Temperature: 20±5oC
Voltage charge time:1 min
Voltage charge: 100Vdc
Performance
≥3×104MΩ for C≤0.33μF
≥1×104MΩ for C>0.33μF
TEST METHOD AND PERFORMANCE
Test conditions
Temperature: 40±2oC
Relative humidity (RH): 90-95%
Test duration: 500 hours
Performance
0.66×rated withstand voltage 60sec.
Capacitance change (△C/C):≤5%
Dissipation Factor (△DF):≤200% of initial specified value
Insulation resistance: ≥50% of initial limit
Endurance:
Test conditions
Temperature: 100±3oC
Test duration: 1008h
Voltage applied: 440Vac
Capacitance change (△C/C):≤5%
Dissipation Factor (△DF):≥0.06% of increased value
Insulation resistance: ≥50% of initial limit
Soldering heat resistance:
Test conditions
Solder bath temperature: 260±5oC
Solder time: 5±1 sec
Performance
Capacitance change (△C/C):≤3%
请问是按哪一种测:1200VDC 60S 或 2100VDC 1S
还是 : 0.66*1200VDC 60S 或 0.66*2100VDC 1S
还有漏电流应该不能大于多少算正常?上面都没提到
