High Reliability "HR" Capacitors
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.
Quality Assurance Provisions
Every lot undergoes the following inspection and tests:
•
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.
Capacitance:
All parts are tested at 25°C and 1VACRMS in accordance with Method 305 of
MIL-STD-202.

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.
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.
Visual:
Performed on pieces in accordance with Presidio internal workmanship criteria.
Mechanical:
Level 1 AQL 1% in accordance with Presidio's catalog.
Element Evaluation (optional):
A MIL-PRF-38534 Appendix C Passive Element Class H
element evaluation is available where the customer requires this testing. Element
evaluation is not required on each lot, and must be specified on the purchase order.
Operating Temperature Range:
-55°C to +125°C
