Material High Saturation Nickel/Iron Core.

Inductance Tested at an AC drive level which does not affect the initial

permeability of the core, the DC drive level was 0 amps.

Incremental Current The DC current which reduces the inductance

value to the percentage drop tabulated.

Inductor Base Formed from a high temperature thermoplastic capable of

withstanding approx. 600°F for short periods of time.

Marking API, Inductance, and Date Code.
