FLLD31K6APVI1 is one of the power line filter modules developed by TDK, specifically designed for applications such as motor control, contactors, and relay coils, to reduce EMI noise entering or being generated by an electronic equipment. This kind of module provides a very high rate of filter capability in less space and minimal cost.

A power line filter generally consists of an inductor or an inductive element, usually a toroidal coil. This inductor is then connected to a capacitor, connected to ground.

The FLLD31K6APVI1 module consists of a three-pole, high performance, single-phase EMI power line filter. It offers excellent attenuation of differential-mode (DM) and common-mode (CM) interference on power supply lines, with a rated current up to 6A. This module works in frequency bands ranging from 4MHz to 1GHz.

The module also features an extremely low filter insertion loss, high differential-mode attenuation, high common-mode attenuation, wide band differential-mode attenuation, and wide band common-mode rejection. It also has low thermal resistance, good RF shielding and low leakage current. The inductor in the module is constructed of high-permeability material with low DC resistance and high frequency characteristics, thus allowing for improved common-mode attenuation and power dissipation.

The FLLD31K6APVI1 is designed for use in power line filtering equipment, and in electronic applications, such as inverter-fed motor drives, PLC control systems, and compressors. These filters can be used to help reduce any kind of EMI noise that may interfere with the normal operation of electronic equipment. The module also helps reduce EMI hearing on motor coils, when used as part of an EMI filter system.

The working principle behind the FLLD31K6APVI1 filter module is quite simple. It operates by preventing (attenuating or rejecting) noise from entering or being generated by an electronic equipment. The module creates an impedance or interruption in the current and voltage at specific frequencies between the source and load. Noise signals that cross the impedance are filtered from the main signals, causing only a small amount or insignificant effect on the desired signals.

The FLLD31K6APVI1 filter module is a great solution for applications where EMI noise reduction is needed. It offers excellent attenuation of EMI, and provides a wide-band common-mode rejection, making it suitable for a variety of applications. The device also has a low insertion loss, high differential-mode attenuation, and wide-band common-mode rejection.
