VHF chokes for power line applications
Rated voltage 500 V dc/ac1)
Rated current max. 1 A
Construction
■ Round 6-aperture ferrite core
■ With or without insulating sleeve
Features
■ The selected core material provides
maximum impedance in the relevant
frequency range of 50 to 200 MHz
■ An insulating sleeve prevents
any turn-to-turn short circuits
Applications
■ Broadband interference suppression in
electrical systems and equipment in the
RF and VHF range
■ Reduction of radiated interference in
broadcasting and TV receivers
