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.

The wound toroid inductor is secured in the housing with an epoxy resin. The
housing material is a Liquid Crystal Polymer, off-white in color. Marking, applied by
Laser Label, designates one coil termination lead with an indicator dot (see Figure 1).
The second coil termination lead is designated by ribs on the side of
the housing. The remaining leads are no-connection leads. The copper leads are
tin-lead plated. The larger products (HMGPT-47 and larger) have a brass insert
