MIL-PRF-39003 / MIL-C-39003 CSR Tantalum Capacitors

Electronic Expediters inventories and sources capacitors associated with the MIL-PRF-39003 military capacitor family, historically referenced under MIL-C-39003 terminology. Buyers may encounter these parts by the current MIL-PRF-39003 designation, legacy MIL-C-39003 references, M39003 military part numbers, or CSR military style numbers.

MIL-PRF-39003 and CSR Capacitor Identification

MIL-PRF-39003 is the military performance specification family for fixed electrolytic tantalum capacitors using solid electrolyte construction and established reliability requirements. Individual specification sheets define particular CSR styles and configurations.

Search M39003 and CSR Capacitors by Exact Part Number

MIL-PRF-39003 procurement requirements are commonly specified using an M39003 slash-sheet part number or a CSR style number. Expediters maintains individual inventory records for thousands of matching part numbers, including manufacturer, alternate part number, date-code information and quantity where those fields are available in the source record.

When a complete M39003 or CSR part number is available on a bill of material, drawing or sourcing request, use the exact part number in the Expediters site search for the most precise result.

Legacy and Hard-to-Find M39003 / CSR Capacitors

MIL-PRF-39003 components remain relevant in long-life military, aerospace and industrial programs. Expediters supports sourcing for current inventory as well as legacy, obsolete and difficult-to-locate CSR and M39003 capacitor requirements.

M39003 Part Numbers, Slash Sheets and CSR Styles

The broader MIL-PRF-39003 specification defines the family requirements, while individual specification sheets and complete M39003 part numbers identify specific capacitor configurations. CSR style designations provide another common way these components appear in procurement records and historical documentation.

A family-level match should not be treated as proof that two capacitor part numbers are interchangeable. Buyers should verify the complete required part number, applicable slash sheet, electrical characteristics and procurement documentation before substitution.

MIL-PRF-39003 / CSR Questions

What type of capacitor is covered by MIL-PRF-39003?

MIL-PRF-39003 covers fixed electrolytic tantalum capacitors using solid electrolyte construction and established reliability requirements. Individual specification sheets define specific styles and configurations.

What is a CSR capacitor?

CSR is a military style designation used for capacitor configurations within the MIL-PRF-39003 specification family. Examples include CSR09, CSR13, CSR21, CSR23, CSR33 and CSR91.

What does M39003 identify?

M39003 identifies the military part-number family associated with MIL-PRF-39003. A complete M39003 part number normally includes additional slash-sheet and detail information needed to identify the specific component.

Why might a BOM say MIL-C-39003 instead of MIL-PRF-39003?

Older drawings, bills of material and procurement records may retain legacy MIL-C terminology. Current Department of Defense documentation uses MIL-PRF-39003 terminology, so both references can be encountered when sourcing older military components.

Can Expediters help source obsolete CSR capacitors?

Yes. Expediters supports sourcing for current, legacy and difficult-to-find electronic components. Search the exact CSR or M39003 part number first, then contact Expediters when additional sourcing assistance is needed.
