• INDUCTANCE VS. CURRENT:

Inductance will fall off as DC Current is increased.

(See Inductance vs. Current graph).

• FREQUENCY RESPONSE:

Wide-band frequency response to 1 megaHertz.

• CURRENT LIMITATION:

The maximum allowable currents are defined by the internal

“hot-spot” temperatures which are limited to 130°C, including

ambient.
