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.

Operating Temperature Range

–40°C to +125°C

Power Dissipation

0.285 Max. (Watts)

Weight Max.

(Grams) 2.00

Packaging

Bulk only

Current Rating

Based on a 35° C max. rise from 90°C

ambient.
