• INDUCTANCE VS. CURRENT:
• INDUCTANCE VS. FREQUENCY:
• FREQUENCY RESPONSE:
• CURRENT LIMITATION:
TEMPERATURE RISE VS. RATED CURRENT
Max. Ambient plus Rise = 125 C
Inductance will fall off as DC Current is increased.
(See Inductance vs. Current graph).
Inductance roll-off versus Frequency approximates 3% at
1 megaHertz.
Wide-band frequency response to 1 megaHertz.
The maximum allowable currents are defined by the internal
“hot-spot” temperatures which are limited to 130°C, including
ambient.
