“HOW TO ORDER A STANDARD PART”
For applications where reliability, but not full military screening is required, Presidio recommends its high reliability
“HR”
capacitors. The “HR” code signifies use of the test program below, or the use of a customer Source Control
Document (SCD) that includes voltage conditioning.

a) Voltage Conditioning —
All parts receive a voltage
conditioning at 2X rated voltage and 125°C for a minimum
of 8 hours. An accelerated voltage conditioning, following
MIL-PRF-55681 guidelines, may be used at Presidio’s
discretion.
d) Dielectric Withstanding Voltage (DWV) —
All parts are
tested at 2.5X rated voltage in accordance with Method
301 of MIL-STD-202, or according to EIA/MIL Standards.
e) Insulation Resistance (IR @ 25°C) —
All parts are tested
at 25°C and rated voltage in accordance with Method 302
of MIL-STD-202. The minimum IR required is 100,000
megohms or 1,000 megohm-microfarads.
