MIL-C-18312 CH Capacitors - Legacy Military Inventory
Electronic Expediters stocks legacy CH capacitors associated with MIL-C-18312 and M18312 military part numbers. MIL-C-18312 covered fixed metallized paper-plastic or plastic-film dielectric capacitors in hermetically sealed metal cases.
MIL-C-18312 has been canceled. Certain detail specifications direct future acquisition to corresponding MIL-PRF-39022 sheets, making both the historical CH designation and the newer CHR/M39022 family important when researching replacement requirements.
Examples found in Expediters inventory include CH09A1NE104K, CH05A1RA823J, CH08A1NE105K, CH54B1NF475K and M18312/02-0177.
MIL-C-18312 and CH Capacitor Identification
Legacy drawings may identify these capacitors by CH style, an M18312 slash-sheet number or a manufacturer part number. Because the specification is canceled, exact identification is particularly important when supporting installed military equipment.
Search M18312 and CH Capacitors by Exact Part Number
Search the complete M18312 or CH identifier whenever available. Expediters' live inventory may include multiple manufacturers, date codes or historical cross-references for the same military requirement.
