Double - Aperture Cores

Two-aperture RID Cores (Transfluxers)

TDK (Epcos) produces 6 standard sizes of double-aperture ferrite cores (DL-shapes).

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

Available DL-cores in stock and on order
