Power line filter modules are electrical components that act as a filter between equipment and an AC power line, using capacitors, inductors, and chokes to suppress electromagnetic interference (EMI) from both line-conducted and radiated noise. The NAP-04-332 is a type of power line filter module designed to provide high attenuation at both common mode and differential mode, while providing reliablility and low insertion loss. This module is perfect for a variety of applications, ranging from home appliances and power supplies to medical equipment.

The NAP-04-332 power line filter module features an isolated construction in a three-phase configuration with single-phase EMI filters integrated into the same package. This module is rated from 380VAC to 400VAC at 50/60 HZ, with a current handling capacity of 16A. It is composed of three capacitive, inductive, and choke-filled cells, as well as two metal oxide varistors (MOVs). This design allows for increased reliability and wider operational temperature range.

The working principle of the NAP-04-332 power line filter module is simple. It works by filtering EMI from both conducted and radiated noise travelling through the line. It operates by impedance matching, allowing the module to divert EMI away from the connected equipment. The capacitive and inductive elements in the module act to attenuate common and differential mode currents, while the MOVs provide the necessary overvoltage protection. The choke coils provide additional attenuation of conducted EMI, as well as help suppress leakage current.

The NAP-04-332 power line filter module is perfect for applications that require high attenuation with low insertion loss. Its three-phase construction ensures a wide operational temperature range. It is ideal for use with single-phase equipment such as home appliances, power supplies, and medical equipment. With its robust construction and low failure rate, the NAP-04-332 is an excellent choice for any filtering application.
