Datasheet

558 08/01
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
Overview of available types
1) Cores made of NiZn ferrite may exceed the specified dimensions by up to 5 %.
2) In accordance with DIN 41279, shape G.
3) Magnetic characteristics and A
L
value are based on winding of center leg.
4) Double-aperture cores are available with parylene coating on request. In this case the thickness of the coating is
approx. 10 to 15 µm. Ordering code for coated version: B62152-P…
