PERFORMANCE SPECIFICATION SHEET
CAPACITORS, FIXED, ELECTROLYTIC (ALUMINUM OXIDE)
(POLARIZED), NON-ESTABLISHED RELIABILITY AND ESTABLISHED RELIABILITY
STYLES CU16 (UNINSULATED), CU17 (INSULATED), AND CUR17 (INSULATED)
STYLE CU16 INACTIVE FOR
DESIGN AFTER 23 MARCH 1972
This specification is approved for use by all Depart-
ments and Agencies of the Department of Defense.
The requirements for acquiring the capacitors described herein shall consist
of this specification sheet and MIL-PRF-39018.
NOTES:
1. Dimensions are in inches.
2. Metric equivalents are given for general information only and are based upon 1.00 inch = 25.4 mm.
3. These capacitors are not intended to be mounted by their leads.
4. For .625 diameter case, the leads shall be .032 +.008, -.002 diameter and for all other diameter cases the
leads shall be .040 +.008, -.002 diameter.
5. The “D” dimensions for styles CU17 and CUR17 shall be not more than .008 (0.20 mm) larger than the
specified bare case diameter.

1/ The ripple current values shown are representative values not supported by test data.
2/ Dash number will include the letter "H" to indicate high frequency vibration (when applicable) or "-" will be deleted.
3/ The last letter in the dash number will indicate the applicable FR level symbol ("M", "P", "R", or "S"). For style CUR17 parts with random vibration, the letter R shall
be used in place of the dash between the specification sheet number and the dash number (i.e., M39018/03R1052M or M39018/03R1252M).

APPLICATION NOTE:
Ripple current: The maximum permissible ripple current for these capacitors can be determined from table III.
The appropriate multiplier from this table should be used where operation at other frequencies or temperatures
is desired. Operation of these capacitors outside the limits of 60 to 100,000 Hz is not recommended.
