Electronic Expediters stocks fixed aluminum-oxide electrolytic capacitors associated with MIL-PRF-39018 and the legacy MIL-C-39018 designation. This family includes CU and CUR style numbers as well as M39018 military part numbers used in established-reliability and non-established-reliability applications.
Examples found in Expediters inventory include CUR19BH392UP3, CU17BJ471SP3, CUR17BJ331SP3, CU13BH221SP3 and M39018/03-0639.
MIL-PRF-39018 and CU / CUR Capacitor Identification
MIL-PRF-39018 covers fixed aluminum-oxide electrolytic capacitors. Procurement records may identify a part by its CU or CUR style, by an M39018 slash-sheet PIN, or by a manufacturer number corresponding to the military requirement.
Search M39018, CU and CUR Capacitors by Exact Part Number
Use the complete military PIN whenever possible. Small differences in style, voltage, capacitance, insulation, reliability level or specification sheet can identify materially different parts.

CU and CUR Inventory for Legacy Military Electronics
Expediters' MIL-PRF-39018 inventory includes legacy CU and CUR parts from manufacturers such as Sprague and other historical military-component suppliers. Availability is presented from live inventory records rather than a representative product list.
M39018 Slash Sheets and Style Numbers
M39018 part numbers are tied to specification sheets defining the physical and electrical requirements for the capacitor. Older documentation may use MIL-C-39018 while later documentation uses MIL-PRF-39018. Both references are relevant when searching historical procurement records.
