Double-aperture cores
Double aperture cores
Primarily used for broadband
transformers up to high frequencies
Application examples
■ SIFERRIT material N30 for low frequencies
and for pulse applications
■ SIFERRIT material K1
for matching transformers and baluns
up to about 250 MHz in antenna feeders
or in input circuits of VHF and TV receivers

1) Cores made of NiZn ferrite may exceed the specified dimensions by up to 5%.
2) Magnetic characteristics and AL value are based on winding of center leg.
3) Double-aperture cores are available with parylene coating on request. In this case the thickness of the coating is
approx.
