GENERAL SPECIFICATIONS
NOTE: Electrical characteristics at + 25 °C unless otherwise
Insulation Resistance (IR):
At + 25 °C and rated voltage 100,000 MΩ minimum or
1000 ΩF, whichever is less.
At + 125 °C and rated voltage 10,000 MΩ minimum or
100 ΩF, whichever is less.
specified.
Capacitance Range: 1.0 pF to 0.47 µF.
Voltage - Temperature Limits:
BP: 0 30 ppm/°C from - 55 °C to + 125 °C, with 0 Vdc applied.
BX: 15 % from - 55 °C to + 125 °C, with 0 Vdc applied.
Dielectric Withstanding Voltage (DWV):
This is the maximum voltage the capacitors are tested for
a 1 to 5 second period and the charge/discharge current does
not exceed 50mA
Dissipation Factor (DF):
BP: 0.15 % maximum; BX: 2.5 % maximum.
Test Frequency: 1 MHz 50 kHz for BP capacitors ≤ 1000 pF
≤ 100V DC : DWV at 250 % of rated voltage.
and for BX capacitors ≤ 100 pF.
All other BP and BX capacitors are tested at 1 kHz 50 Hz.
