Hybrid choke eliminates two extra components

17 November 2004 Electronics Technology Information Security

Murata developed a device to suppress conducted and radiated disturbance with using one component instead of the usual three. The company's hybrid choke coil (HCC) is both a common mode and a differential mode choke, which provides better noise suppression at frequencies above 30 MHz than discrete filters for each mode. The PLY17 range of HCCs, in a 24,5 x 22,5 mm package 12,5 mm high, offers 10 common mode inductance values between 1,0 and 9,3 mH. Each value comes as standard or high performance option.
