MIL-PRF-15733J
3.22 Life. When tested as specified in 4.6.19, filters shall meet the following requirements:
Dielectric withstanding voltage - - - - - - - - - - - - - - - - As specified in 3.8.
Insulation resistance - - - - - - - - - - - - - - - - - - - - - - - Not less than 30 percent of the value specified in 3.10.
Insertion loss - - - - - - - - - - - - - - - - - - - - - - - - - - Shall meet initial requirement, unless otherwise
specified (see 3.1).
Visual examination - - - - - - - - - - - - - - - - - - - - - - - - There shall be no visible mechanical damage.
Capacitance (when specified) - - - - - - - - - - - - - - - - Change not more than the value specified (see 3.1)
from the initial measured value.
3.23 Resistance to solvents. When filters are tested as specified in 4.6.20, there shall be no evidence of
mechanical damage and the marking shall remain legible.
3.24 Solderability.
3.24.1 Solderability of terminals (soldered terminals only). When filters are tested as specified in 4.6.21.1, the dipped
surface of the leads shall be at least 95 percent covered with continuous solder coating. The remaining 5 percent of the
lead surface may show only small pinholes or voids and these shall not be concentrated in one area. Bare base metal
and areas where the solder dip fails to cover the original coating are indications of poor solderability, and shall be cause
for rejection.
3.24.2 Solderability of mounting termination (when applicable). When filters are tested as specified in 4.6.21.2, the
joint shall be at least 95 percent covered with continuous solder coating. There shall be no evidence of leaching (loss
of metallization). After the test, filters shall meet the following requirements:
Insulation resistance (+25°C) - - - - - - - - - - - - - - - - -Shall meet initial requirements (see 3.1).
Capacitance - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Shall meet initial requirements (see 3.1).
3.25 Marking (see 4.6.1).
3.25.1 Full marking. Each filter shall be marked in accordance with method I of MIL-STD-1285 with the following
information:
Example
a. Military part number.
M15733/74-0013
b. Manufacturer's CAGE.
12345
c. Manufacturing date code and lot symbol.
0211A
600 V dc, 250 V ac at +125°C
d. Voltage rating and maximum operating temperature.
e. Current rating.
5 Ampere
f. Terminal identification or circuit diagram.
L1
(Non-symmetrical filters only)
g. Maximum operating power frequency (for ac rated filters).
400 Hz
3.25.2 Minimum marking. When the physical size of the filter precludes the marking of the information in 3.25.1,
the minimum marking required shall be as specified in the specification sheet (see 3.1). In those cases where full
marking requirements are not on the filter, the full marking shall be marked on the unit package.
3.26 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally
preferable materials should be used to the maximum extent possible provided that the material meets or exceeds the
operational and maintenance requirements, and promotes economically advantageous life cycle costs.
3.27 Workmanship (see 4.6.1). Filters shall be processed in such a manner as to be uniform in quality and shall
be free from cold soldering, corrosion (see 3.17), pits, dents, cracks, rough edges, misalignments, and other defects
that will affect life, serviceability, or appearance.
