D SERIES METALLIZED POLYESTER CAPACITORS

 PARAMETRIC TREND CURVES AND ACCEPTANCE CRITERIA  

CAPACITANCE

Reference MIL-STD-202, Method 305

Test Frequency: 1000 Hz

Temperature: +25°C

Capacitance Change Over Temperature.

Acceptance Limits:

@ -55°C = -7% Maximum Change

@ +85°C = +5% Maximum Change

@ +125°C = ±16% Maximum Change

 

DISSIPATION FACTOR

Reference MIL-STD-202,

Method 306

Test Frequency: 1000 Hz

Temperature: +25°C

Acceptance Limit: 0.65% Maximum

  

INSULATION RESISTANCE

Reference MIL-STD-202, Method 302

Electrification shall be at rated voltage

or 500 VDC, whichever is less and for

a time not greater than 2 minutes.

VOLTAGE RATING

100% of listed voltage rating from -55°C to +85°C,

derate linearly to 50% of the listed voltage rating at +125°C.

 VOLTAGE TEST

Reference MIL-STD-202, Method 301. Surge current is limited to 1 ampere maximum. Voltage applied for 1 minute (maximum) @ +25°C. Ground test is performed terminal to case (where the case is not a terminal) at 200% of the DC voltage rating. Dielectric strength test is performed terminal to terminal at 150% of the DC voltage rating.
