1. Electrical specifications
at 25ºC.
2. Tested at 100kHz.
3. Operating temperature
range: -40ºC to +130ºC.
Operating temperature
is a combination of
ambient temperature plus
temperature rise.
4. Meets UL 94V-0.
5. Specifications shown are
for an inductor with a
55ºC temperature rise.
The core loss is 10% of
the copper loss when
operating at 500kHz.
6. Please remember it is
much easier to remove
heat from a copper-loss
dominated design than
from a core-loss domi-
nated design.
Specifications subject to change without notice.
