HIGH RELIABILITY EXTENDED RANGE CHIP CAPACITORS
For space flight applications that require the highest level of reliability,
Presidio recommends its high reliability extended range chip
capacitors. Tested to the requirements of MIL-PRF-123, Presidio
manufactures these chips on the same manufacturing line as its
military products. Please note these capacitors are NOT MIL-qualified.
Unless noted in the data sheet, the parts do meet the MIL-PRF-123
design requirements for dielectric thickness and electrode composition.
All parts are manufactured with
PRECIOUS METAL ELECTRODES.
DESTRUCTIVE PHYSICAL ANALYSIS (DPA) —
A representative
sample is pulled from each lot and examined per EIA RS469 and
to verify adherence to Presidioʼs design criteria. Sample size is per
MIL-PRF-123.
FORMERLY THE PRESIDIO COMPONENTS, INC. “#M123” DRAWING
NASA S-311 SPECIFICATION
Most of these chips are qualified to the
NASA S-311 drawing. For more information
click on the NASA S-311-P-829 link on
Presidio’s website:
www.presidiocomponents.com
Every lot undergoes the following inspection and tests.
QUALITY ASSURANCE PROVISIONS
THERMAL SHOCK —
All parts are temperature cycled for 20
cycles to MIL-STD-202 Method 107, Condition A, except that max
temperature is 125°C.
ULTRASONIC SCANNING SAMPLE —
This screening sample
will be performed on lots to assure the highest quality
microstructure. 100% ultrasonic scanning is not required for each
lot, and must be specified on the customer order. Separate charge
applies for 100% ultrasonic scanning.
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 interval
that failures are less than .1% or 1 piece during the last 48 hours
of the test. Method follows MIL-PRF-123. Resistors, instead of
fuses are acceptable.
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.
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.
VISUAL —
A 100% inspection is performed IAW MIL-PRF-123
Appendix B.
MECHANICAL —
Level 1 AQL 1% in accordance with
MIL-PRF-123.
* HUMIDITY, STEADY STATE, LOW VOLTAGE —
A sample of
12 pieces is pulled from each lot and tested per MIL-PRF-123.
* THERMAL SHOCK AND LIFE TEST —
A sample is pulled from
each lot. 100 Thermal shock cycles are performed and Life Test is
performed for 1000 hours at 2X rated voltage and 125°C. Sample
size and method follows MIL-PRF-123.
DIELECTRIC WITHSTANDING VOLTAGE (DWV) —
All parts are
tested at 2.5X rated voltage in accordance with Method 301 of
MIL-STD-202.
Product will be packaged in individual waffle trays. Tape and reel
option is available.
MARKING (Optional for sizes 0805 and larger only) —
Parts will
not be marked unless marking is specified on the PO. If marking is
specified, a color letter will be used per Presidioʼs chip marking
system.

STD-202. The minimum IR required is 100,000 Megohms or 1,000
Megohm-Microfarads.
CAPACITANCE —
All parts are tested at 25°C and 1VACRMS in
accordance with Method 305 of MIL-STD-202.

• DPA REPORT
• GROUP A & B ATTRIBUTE DATA SHEET
• LIFE TEST AND HUMIDITY VARIABLES DATA SHEET.
* Group B required for flight parts. Parts for engineering models
may be subject to lesser screening requirements.
