HIGH RELIABILITY “CR” CAPACITORS
(TESTED SIMILARLY TO MIL-PRF-55681)
For applications that require a high level of reliability, Presidio recommends its high reliability
“CR”
capacitors. Tested
similarly to MIL-PRF-55681 Group A, Presidio manufactures these chips on the same manufacturing line as its military
product line. They may be used in both military and space applications. Please note these capacitors are NOT MIL-qualified.
QUALITY ASSURANCE PROVISIONS
Every lot undergoes the following inspection and tests:
a) Destructive Physical Analysis (DPA) —
A 32-piece
sample is pulled from each lot and examined per relevant
sections of EIA 469 and to verify adherence to Presidio’s
internal design criteria.
b) Voltage Conditioning —
All parts receive a voltage
conditioning at 2X rated voltage and 125°C for 100 hours.
An accelerated voltage conditioning, following MIL-PRF-
55681 guidelines, may be used at Presidio’s discretion.
j) Class H 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.
k) Operating Temperature Range:
–55°C to +125°C
i) Mechanical —
Level 1 AQL 1% in accordance with
this catalog.

Product will be packaged in individual waffle trays.
Data will be sent with each shipment including:
a) Destructive Physical Analysis Report (optional) —
Destructive Physical Analysis (DPA) report and photographs
for each lot. Extra charge may apply.
b) Certificate of Compliance —
A Certificate of
Compliance will be sent with each shipment.
c) Class H Element Evaluation —
If a Class H element
evaluation is required, all variables test data for subgroup
3 tests will be included in the data package.
e) 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.
f) 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.
EXAMPLE PART NUMBER
g) Percent Defective Allowed (PDA) —
The cumulative
PDA after voltage conditioning is 8%. Pieces rejected as out
of tolerance for capacitance or visual screening will be
removed from the lot but not counted in the PDA calculation.
h) Visual —
Performed on pieces in accordance with
Presidio internal workmanship criteria.
