MIL-PRF-39001 / MIL-C-39001 CMR Mica Capacitors
Electronic Expediters inventories and sources capacitors associated with the MIL-PRF-39001 military capacitor family. Older drawings, bills of material and procurement records may use legacy MIL-C-39001 terminology. Components within this family are identified through CMR style-based Part or Identifying Numbers.
MIL-PRF-39001 and CMR Capacitor Identification
MIL-PRF-39001 defines general requirements for fixed mica-dielectric capacitors in established-reliability and non-established-reliability configurations. The military Part or Identifying Number begins with the applicable CMR style followed by coded electrical and reliability characteristics.

Search CMR Capacitors by Exact Part Number
MIL-PRF-39001 requirements are commonly identified directly by a CMR Part or Identifying Number. Expediters maintains individual inventory records for CMR military capacitor part numbers, including manufacturer, alternate part number, date-code information and quantity where those fields are available in the source inventory record.
When a complete CMR part number appears on a bill of material, drawing or sourcing request, use that exact number in the Expediters site search for the most precise result.

Legacy and Hard-to-Find CMR Mica Capacitors
MIL-PRF-39001 mica capacitors remain relevant in military, aerospace, communications and long-life electronic systems. Expediters supports sourcing for current inventory as well as legacy, obsolete and difficult-to-locate CMR capacitor requirements.
Understanding MIL-PRF-39001 CMR Part Numbers
The MIL-PRF-39001 Part or Identifying Number begins with the CMR style designation. Additional characters identify characteristics such as capacitance, capacitance tolerance, operating temperature range, rated voltage and product level.
For example, the general specification illustrates PIN construction using a CMR04-style number. The complete CMR number should be used for procurement rather than relying only on the broader specification or style family.
A shared CMR style does not by itself establish interchangeability. The complete part number, applicable specification sheet, capacitance, tolerance, voltage, temperature characteristics and reliability requirements should be verified before substitution.

MIL-PRF-39001 / CMR Questions
What type of capacitor is covered by MIL-PRF-39001?
MIL-PRF-39001 covers fixed mica-dielectric capacitors in established-reliability and non-established-reliability configurations.
What is a CMR capacitor?
CMR is the military style family used for mica-dielectric capacitors covered by MIL-PRF-39001. The style designation forms the beginning of the military Part or Identifying Number.
How are MIL-PRF-39001 part numbers structured?
The military PIN begins with the applicable CMR style, followed by coded characters identifying electrical, temperature, voltage and reliability characteristics.
Which CMR styles are covered by MIL-PRF-39001/5?
MIL-PRF-39001/5 covers styles CMR03, CMR04, CMR05, CMR06, CMR07 and CMR08.
Why might older documentation say MIL-C-39001?
Older drawings, specifications and bills of material may retain the former MIL-C designation. Current Department of Defense documentation uses MIL-PRF-39001 terminology, so both references may appear when sourcing legacy military capacitors.
Can Expediters help locate obsolete CMR capacitors?
Yes. Expediters supports sourcing for current, legacy and difficult-to-find electronic components. Search the exact CMR part number first, then contact Expediters when additional sourcing assistance is required.
