The standard inductance value tolerance is +/-10% when measured at 1 Khz, (I =0).

Inductance values and Q 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 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.
