Circuit board filtering module is the most suitable product for DC/DC power supply to suppress the noise. Compliance with the military standard, the working temperature is from -55°C to +125°C.

Switching power supply generally introduces common mode noise in the frequency range from 10 kHz ~ 50 MHz or even higher. Therefore, to effectively reduce these noises, the common mode inductor shall have a high enough impedance. To achieve this specification, the high permeability Manganese-zinc ferrite and the amorphes material are the most appropriate choices. The Common Inductor's impedance Zs consist of the inductance Xs and the resistance Rs.
