Coupled Filter Inductors
·
·
·
·
·
·
For precision filter applications to beyond 10 MHz
Standard inductance tolerance as low as 5%
Can be configured as a coupled inductor, common-
mode filter, or differential-mode filter
Superior THD and IMD performance with or without
DC bias
Unmatched energy storage in a 5mm package
Drop-in upgrades for many competitive designs
