Common Mode Chokes
All Pico Electronics common mode chokes are manufactured to MIL-PRF-27, Grade 5, Class S. These chokes are well suited for use in switching regulators, AC-DC power supplies, DC-DC power supplies, and all types of electrical equipment where the elimination of electromagnetic interference is important. Electrical equipment will generate noise due to switching operations of MOSFETs, SCR’s, relays, triacs, etc. By using these chokes, noise being fed back to the power line is minimized to an acceptable level and this noise will not interfere with other equipment operating on the same power line. Options are available between dual winding or 3 phase and operation can be designed in differential mode as well. The HCM series provides maximum current capability in the smallest industry size, suitable for harsh environments.
