A Power Line Module is an electronic device that filters out unwanted electromagnetic interference in power supply lines. FC100V20A-G is a type of power line filter module, designed for applications at frequencies from 10kHz to 500kHz. In this article, we will discuss the application fields and the working principle of FC100V20A-G.

Application Field

FC100V20A-G is an integrated solution for power line filtering. It is designed to reduce common-mode noise and differential-mode noise on wireline signal lines, while providing high attenuation characteristics over a broad frequency range of 10kHz to 500kHz. The module features a low profile, an integrated peak current limiter and a snap-in mounting hole. Thus, it is suitable for versatile applications, including power supplies, motor drives, automotive, military and aerospace designs.

Compared to traditional discrete filter solutions, the FC100V20A-G provides superior attenuation characteristics with a compact module size. In addition, the module is compliant with the EN 55022, CISPR 22, and IEC 60950-3 industry standards.

Working Principle

FC100V20A-G contains a power inductor, capacitor and a thermal switch. The power inductor forms a magnetic field when current flows through it, and the capacitor blocks the high frequency noise, while allowing the low frequency signal to pass. The combination of these components helps reduce noise and interference on the power line.

When the current flowing through the power inductor exceeds a predetermined level, the thermal switch is activated and the circuit is interrupted. This reduces the risk of damage to components due to excessive current. The integrated peak current limiter also helps to limit the current to a safe level to protect the components.

The FC100V20A-G also contains a shielded housing and an internal damping line. The damping line is designed to absorb energy at high frequencies and reduce the ringing effect. The shielded housing helps to reduce electromagnetic interference by providing increased shielding capacity.

With its integrated peak current limiter, low noise attenuation and high frequency damping, FC100V20A-G is an excellent choice for filtering power supply lines. It provides a cost effective solution for filtering noised caused by power line applications that operate at frequencies from 10kHz to 500kHz.
