Hybrid choke coils combine common and differential modes

A new range of 20 hybrid choke coils, the Murata PLY17 Series from Micromark C&CD, combine common and differential suppression modes in a single package.

Common mode inductance values range from 0.49mH to 9.3mH, with equally variable differential inductance values, and suppression performance above 30MHz is enhanced by a patented winding technique. Maximum rated current is 0.6A for 9.3mH common mode inductance, increasing to 3.0A for 1.0mH values. Insertion loss is approximately 20dB at 100MHz.

The footprint of the PLY17 Series is only 24.5 x 22.5mm, and with four through-hole mounting pins spaced at 15mm x 12.5mm the coils save both board space and material costs.
