are designed using stable powdered iron core material. The toroidal core inductor design

values and Q values are measured on an HP 4284A LCR meter. Since inductance values vary 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 40 deg. C rise in case

temperature. These inductors are designed to meet the applicable portions of MIL-C-15305,

Grade 1, Class B. The operating temperature range is -55 to +125 deg. C. and the inductors are

capableof withstanding500Vdc@50uAappliedbetweenthecoilandthecase.
