High Reliability "SR" Capacitors (Tested similarly to MIL-PRF-123 Group A) 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. 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 relevant sections of EIA 469 and to verify adherence to Presidio's internal design criteria. Sample size is per MIL-PRF-123. * 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. * Thermal Shock: All parts are temperature cycled for 20 cycles in accordance with MIL-PRF123. * Voltage Conditioning: All parts receive a voltage conditioning at 2X rated voltage and 125C 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-PRF123 except resistors are used in place of fuses. * Insulation Resistance (IR @ 125C): All parts are tested at 125C 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, or according to EIA/MIL Standards. * Insulation Resistance (IR @ 25C): All parts are tested at 25C 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 25C and 1VACRMS in accordance with Method 305 of MIL-STD-202. * Dissipation Factor (DF): Voltage Rating NPO 16 / 25 .15% 50 .15% BX 2.5% 2.5% X7R 3.5% 2.5% * 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: Performed on pieces in accordance with MIL-PRF-123 Appendix B. * Mechanical: Level 1 AQL 1% in accordance with MIL-PRF-123. * 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. * Operating Temperature Range: -55C to +125C 7169 Construction Court, San Diego, CA 92121 USA * Tel: 858-578-9390 * Fax: 800-538-3880 or 858-578-6225 Web: www.presidiocomponents.com * Email: info@presidiocomponents.com High Reliability "SR" Capacitors (Tested similarly to MIL-PRF-123 Group A) Standard Packaging Product will be packaged in individual waffle trays or tape and reel as specified by customer.
