Power Line Filter Modules, or PLFs, are specialized components that help reduce the amount of power line noise in industrial applications. The FLLD3320APVI1 is a type of PLF with an integrated counter-current circuit topology for improved EMI/RFI noise filtering. It is an ideal solution for high-end applications such as those in medical, military, aerospace, and industrial automation.

The FLLD3320APVI1 is designed to block high-frequency noise from the power line while allowing low-frequency signal components to pass through it. It provides a common mode noise attenuation range of 0.1 to 125 megahertz (MHz) for single line power systems, while its differential mode attenuation coverage ranges from 0.5 to 40 MHz.

The FLLD3320APVI1 incorporates a variety of features that are optimized for superiority in EMI/RFI filter performance. It has a dielectric strength of 12 kilovolts, 150% voltage surge capability, and 400V transient voltage surge protection. The FLLD3320APVI1 utilizes a three-terminal design, with the center terminal connected to ground, allowing for easy connection to the main power line. Additionally, its small form factor (0.8” x 0.6” x 0.16”) allows for easy installation in a variety of applications.

The FLLD3320APVI1 utilizes a pulse-width modulation (PWM) controller to trigger a pair of built-in avalanche diodes. When energized, the avalanche diodes slow down the charged particles, while simultaneously blocking high-frequency noise. This technique offers a higher level of noise filtering than a single line filter alone.

The FLLD3320APVI1 also incorporates EMI suppression cores. These cores are designed to reduce the amount of electronic noise that can enter the power system. The cores are made of high permeability ferrite, which is capable of absorbing strong electromagnetic waves and allowing only low-frequency signals to pass.

In addition, the FLLD3320APVI1 is designed with multiple energy storage capacitors. These capacitors store the electrical energy so that it can be released during periods of high frequency noise. This helps reduce the amount of high frequency noise that gets into the power system, preserving the integrity of the signals that are passing through the filter.

The FLLD3320APVI1 is an ideal solution for the most demanding applications thanks to its superior EMI/RFI suppression capability and pulse-width modulation control system. Its compact form factor allows for easy integration into any system, while its multiple energy storage capacitors and integrated counter-current circuit topology help provide superior noise suppression performance in a variety of industrial applications.
