Company are designed for RF/low power applications using stable powdered iron core

material. The fully encapsulated inductor provides a low external magnetic field, a high

self-resonantfrequency,andahighQ.

The standard inductance value tolerance is +/-5% when measured at the frequencies

specified in Table 1. Inductance values are measured on an HP 4284A LCR meter.

Since inductance varies with AC/DC current values, each end application should be

evaluatedtoensureproperreadings.Thetabulatedcurrentratings(RatedI )arethose

calculated to cause a 25 deg. C rise in case temperature. These inductors are designed

to meet the applicable portions of MIL-C-15305, Grade 1, Class B. The temperature

coefficient of inductance is less than 400ppm/deg. C over the operating temperature

range of -55 to +125 deg. C. Inductors are capable of withstanding 500Vdc@50 uA

The inductor is fully encapsulated in epoxy resin and is housed in a Liquid Crystal

Polymer case, off-white in color. The case dimensions are specified in Table 2. The

case marking is applied by silkscreen using blue epoxy paint. The 4 Phosphor-Bronze
