MS53232B
Application notes:
1. The test fixture in the diagram following shall be used for electrical measurements. Inductance values are effective inductance as indicated on a HP260A, HP190A or equivalent Q meter, when tested in the test fixture. Add 5 percent to Q reading to account for loss of Q in the test jig.
2. Polarization during moisture resistance test is not applicable.
3. Coils are held rigidly by the body during vibration and mechanical shock testing.
4. Resistance to soldering heat test, per method 210, of MIL-STD-202, test condition B, is applicable.
5. For dielectric withstanding voltage, barometric pressure and insulation resistance units shall be placed on
Flat metal plate with leads insulated from surface. Measurement of dielectric withstanding voltage, barometric pressure and insulation resistance shall be between the leads of the coil connected together and the metal
plate.
6. Screw core assembly shall be set at maximum specified inductance value indicated in the electrical characteristics table (initial), prior to all inspection tests. This setting shall not be changed until electrical characteristics (final) measurements are performed.
