Current Rating Based on a 35° C max. rise from 90°C ambient.
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.
Terminals Coated with a 90/10 tin/lead plating.
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.
