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.
