HIGH RELIABILITY “SR” CAPACITORS
For applications that require the highest level of reliability, Presidio recommends its high reliability
“SR”
capacitors. Tested
similarly to MIL-PRF-123 Group A, Presidio manufacturers 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.
(TESTED SIMILARLY TO MIL-PRF-123-GROUP A)
QUALITY ASSURANCE PROVISIONS
Every lot undergoes the following inspection and tests:
a) Destructive Physical Analysis (DPA) —
A representative
sample is pulled from each lot and examined per relevant
sections of EIA 469 and to verify adherence to Presidio’s
internal design criteria. Sample size is per
MIL-PRF-123.
b) Ultrasonic Scanning (optional) —
This screening may
be performed on lots to assure the highest quality
microstructure. Ultrasonic scanning is not required for
each lot, and must be specified on the customer purchase
order.
j) Percent Defective Allowed (PDA) —
The cumulative
PDA after voltage conditioning is 5%. Pieces rejected as out
of tolerance for capacitance or visual screening will be
removed from the lot but not counted in the PDA calculation.
k) Visual —
Performed on pieces in accordance with
MIL-PRF-123 Appendix B.
l) Mechanical —
Level 1 AQL 1% in accordance with
MIL-PRF-123.
c) Thermal Shock —
All parts are temperature cycled for 20
cycles in accordance with MIL-PRF-123.
d) Voltage Conditioning —
All parts receive a voltage
conditioning at 2X rated voltage and 125°C for a minimum
of 168 hours and a maximum of 264 hours. Voltage
conditioning may be terminated at any time between 168
and 264 hour time intervals when failures are less than .1%
or 1 piece, during the last 48 hours of the test. Tested in
accordance with MIL-PRF-123 except resistors are used in
place of fuses.
e) Insulation Resistance (IR @ 125°C) —
All parts are
tested at 125°C and rated voltage in accordance with
Method 302 of MIL-STD-202. The minimum IR required is
10,000 megohms or 100 megohm-microfarads.
f) 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.
m) Class K Element Evaluation (optional) —
A MIL-PRF-
38534 Appendix C Passive Element Class K element
evaluation is available when the customer requires this
testing. Element evaluation is not required on each lot,
and must be specified on the purchase order.
n) Operating Temperature Range:
–55°C to +125°C
STANDARD PACKAGING
Product will be packaged in individual waffle trays or tape
and reel as specified by customer.
DATA PACKAGE
Data will be sent with each shipment including:
a) Destructive Physical Analysis Report (optional) —
Destructive Physical Analysis (DPA) report and photographs
for each lot will be sent. Extra charge may apply.
b) Certificate of Compliance —
Certificate of Compliance
and attributes test data sheet will be sent with each
shipment.
c) Class K Element Evaluation —
If a Class K element
evaluation is required, all variables test data for
subgroup 3 tests will be included in the data package.
d) Ultrasonic Scanning Report (optional) —
An
ultrasonic scanning report will be sent, including a
typical scan. Extra charge may apply.
i) Dissipation Factor (DF) —

h) Capacitance —
All parts are tested at 25°C and
1VACRMS in accordance with Method 305 of
MIL-STD-202.
g) 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.
