Common Mode Choke
Description
Payton Common Mode Chokes provide an effective, compact, planar solution for excellent suppressing common mode noise from switch mode power supplies lines. The components have very high repeatability, low profile and weight, low leakage flux, and high impedance at applicable frequency.
