Power Line Filter Modules

The B84142C0250S081 is a power line filter module manufactured by the EPCOS brand division of TDK. It is used to filter the AC power supply in order to reduce noise, eliminate interference, protect the circuit device from transient overvoltage, and reduce the ripple of the output voltage.

The B84142C0250S081 power line filter module is mainly used in the power system of medical equipment, laboratory instruments, measurement devices, and other precision equipment. It is also an ideal filter solution for applications such as industrial control systems, frequency converters, electronic appliances, broadcast equipment, and LED lighting.

Working Principle

The B84142C0250S081 power line filter module consists of three sections, including EMC filter, PI filter, and line impedance stabilizer. The EMC filter reduces the conducted noise, while the PI filter helps to attenuate the common-mode noise and output ripple current. Meanwhile, the line impedance stabilizer controls the electrical parameters in the line thus providing surge protection capabilities.

The EMC filter works by acting as a shield, blocking the passage of emissions from one section (input) to another section (output). All emissions are diverted by the filter, which further reduces the noise levels and reduces the loss of signal transmission. The PI filter works by creating an inductance-capacitance filter, which effectively reduces the interference level of the AC power supply, eliminates electromagnetic interference, and improves the power quality.

The line impedance stabilizer works by controlling the electrical parameters. It helps to reduce the surge impedance of the line thus minimizing the pulsation of the voltage. Properly balancing the input of each phase ensures that the power supply is stable and reliable.

The B84142C0250S081 power line filter module is designed to provide a reliable and high-performance solution for power system in various applications. With its filter capabilities, the B84142C0250S081 effectively eliminates the interference noise and provides reliable protection to the circuit devices.
