MIL-PRF Capacitor Specifications We Support
Military Performance Specification (MIL-PRF) documents define the requirements for capacitors used in defense and aerospace applications. Each specification covers a specific capacitor technology and includes requirements for environmental testing, electrical performance, and quality assurance.
| Specification | Capacitor Type | Key Manufacturers | Typical Applications |
|---|---|---|---|
| MIL-PRF-39003 | Solid Tantalum (CKR/CSR) | Vishay/Sprague, KEMET, AVX | Avionics power filtering, decoupling |
| MIL-PRF-39006 | Wet Tantalum (CLR) | Vishay/Sprague | High-rel DC filtering, space systems |
| MIL-PRF-39014 | Ceramic (CKR/CKS) | Vishay/Vitramon, AVX, Presidio | RF bypass, high-frequency filtering |
| MIL-PRF-19978 | Mica (CM/CMR) | CDE, custom sources | Radar, transmitters, precision timing |
| MIL-PRF-55681 | Film (CRH/CFR) | Vishay, CDE, KEMET | Power conditioning, energy storage |
Why Aerospace Teams Choose Specap
Aerospace procurement is fundamentally different from commercial sourcing. Parts may be specified in technical manuals written 20-40 years ago, manufacturers may have been acquired multiple times, and original part numbers may no longer exist in any distributor's catalog. This is where Specap excels:
- Legacy part number expertise — We track the acquisition lineages of Sprague, Sangamo, Mallory, and other legacy manufacturers whose parts are still specified in active military programs.
- Obsolete MIL-SPEC sourcing — When a MIL-PRF part number has been discontinued, our global network can often locate remaining NOS inventory or help identify an approved replacement through the cross-reference process.
- No minimum order — Defense sustainment often requires 5, 10, or 50 pieces — not full production reels. We accommodate small quantities without markups that make small orders uneconomical.
- Rapid response — AOG (Aircraft on Ground) and urgent sustainment requests get priority attention with same-day response on availability and pricing.
- Quality verification — Every capacitor is electrically tested and inspected before shipment, with authenticity verification to prevent counterfeit components from entering the defense supply chain.
