Power Line Filter Modules

FN258HVIT-55-34 is a power line filter module which is used to eliminate interference between the noise source and the sensitive circuit. It provides a simple low cost filter solution for applications that require reliable and effective operation of power line filtering. The module is designed with two capacitors, two inductors, a diode, and a resistor to form a low pass filter circuits. The two capacitors are connected in series and the two inductors are connected in parallel. This configuration helps to provide an effective damping effect and reduce the noise on the power line.

The working principle of the FN258HVIT-55-34 is that the filter module blocks any high-frequency voltage of noise at the power line while allowing the low-frequency voltage to pass through. The inductor provides impedance to the high-frequency noise and the resistor and two capacitors provide the necessary excessive impedance for the noise to be rejected by the low-pass filter. This ensures that the low-frequency voltage signal and any low-frequency noise are passed through the module, while rejecting the high-frequency noise.

The FN258HVIT-55-34 power line filter module is widely used in a variety of applications such as medical, industrial, and consumer. In medical applications, the power line filter module helps to reduce unwanted noise in MRI machines and other imaging systems. In industrial and commercial applications, the filter module helps to reduce noise and interference in communication systems, such as RFID systems, and audio systems. In consumer and home appliance applications, the power line filter module helps reduce interference in televisions, radios, and other equipment. The power line filter module is also used in many power supplies to keep the operating frequency and voltage within specifications, minimizing EMI and providing reliable operation of the equipment.

The power line filter module is constructed with robust materials to ensure reliable operation in a harsh environment. The inductors in the filter module are wound with an aluminum core and insulated with a highly reliable polyimide tape. The two capacitors are also insulated with a polyimide tape and are made from a high-temperature dielectric material. The two capacitors are connected in series to provide the necessary damping effect while the two inductors are connected in parallel to provide effective impedance to the line. Finally, the resistor is made with a non-volatile dielectric material which helps to block vital signals. This makes the power line filter module ideal for use in a wide range of applications, including medical, industrial, and consumer applications. The module is also designed to meet MIL-STD-883D for vibration and serves in a wide variety of applications. The module is also designed to reduce power losses, increase reliability, and reduce production costs.
