FMAD-0955-H210

Power Line Filter Modules

Power Line Filter Modules are used to improve the power line immunity of electronic equipment. By using the power line filter module, it can reduce the electromagnetic interference (EMI) generated from equipment that is connected to the power line and connected to other equipment, and reduce the effect of external interference from other equipment. The FMAD-0955-H210 is one of the most popular power line filter modules in the industry. This article will discuss its application field and working principle.

Application Field

The FMAD-0955-H210 is a compact power line filter module. It has low insertion loss and a wide frequency range. It is suitable for general industrial, industrial control, lighting & voltage control, and information processing equipment. Its high frequency attenuation can effectively suppress low-level harmonic components, eliminate interference from other equipment, and effectively reduce the effect of external interference. It can also protect the equipment from ground potential rise (GPR) caused by lightning in its application environment.

Working Principle

The FMAD-0955-H210 is composed of an electrically conductive Lambda filter and a ferrite filter, both of which work together to filter the power line to a certain extent. The Lambda filter is composed of two inductors and two capacitors connected in parallel. It has the effect of low-pass filtering the power supply and reducing the interference from low-frequency signals. At the same time, the Lambda filter also has the effect of blocking out-of-band signals. The ferrite filter is composed of ferrite cores. It has complex impedance characteristics in the frequency range, which can reduce the interference of medium and high frequency signals.

The FMAD-0955-H210 power line filter module can effectively attenuate the AC power line signals at frequencies between 500KHz and 2MHz. It also has a wide frequency range and is suitable for various types of equipment. In addition, it has excellent performance in terms of interference isolation, leakage current and safety. It is widely used in the field of industrial control, lighting & voltage control, and information processing.
