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.
Quality Assurance Provisions
Every lot undergoes the following inspection and tests:
- Destructive Physical Analysis (DPA): A representative sample is pulled from each lot and examined per EIA RS469 and to verify adherence to Presidio’s design criteria. Sample size is per MIL-PRF-123.
- 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.
- 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.
- 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.
- Dielectric Withstanding Voltage (DWV): All parts are tested at 2.5X rated voltage in accordance with Method 301 of MIL-STD-202.
- 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.
- Capacitance: All parts are tested at 25°C and 1VACRMS in accordance with Method 305 of MIL-STD-202.
- Dissipation Factor (DF): Shall not exceed .15% for NPO – all voltages, 3.5% for X7R at 16/25 volt rated and 2.5% for X7R at 50/100 volt rated.
- 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.
- 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. Group B required for flight parts. Parts for engineering models may be subject to lesser screening requirements.
- Humidity, Steady State, Low Voltage: A sample of 12 pieces is pulled from each lot and tested per MIL-PRF-123. Group B required for flight parts. Parts for engineering models may be subject to lesser screening requirements.
- 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 Presidio’s
chip marking system.
