Material High Saturation Nickel/Iron Core.
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.
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.
