Description
The FLTR100V20 Filter Module is designed to reduce the conducted common-mode and differential-mode
noise on input or output lines of high-frequency switching power supplies. The module has a maximum current
rating of 20 A. It provides high insertion loss throughout the frequency range regulated by the U.S. Federal
Communications Commission (FCC) and the International Special Committee on Radio Interference (CISPR)
for conducted emissions.
The module is 50.8 mm long, 40.6 mm wide, and 12.7 mm high (2.0 in. x 1.6 in. x 0.50 in.) and mounts on a PC
board in a natural convection or forced-air environment.

Introduction
High-density power modules are usually designed to operate at a high switching frequency to reduce the size of
the internal filter components. The small EMI filters internal to the modules are often inadequate to meet stringent
international EMI requirements. Many high-density electronic packaging techniques can increase the noise conducted onto the modules’ input and output lines. For example, the close proximity of switching components to the
input pins increases internal noise coupling; and planar transformers, designed to handle high-power levels in lowprofile packages, have high interwinding capacitance that can increase common-mode current levels. Also, metal
substrates used to facilitate heat transfer from the power train components to an external heat sink add to common-mode noise because of the large capacitance between switching components and the metal substrate.
Many international agencies specify conducted and radiated emissions limits for electronic products. Included
among these are CISPR, FCC, VCCI, and the new CE specifications. Most agency-conducted noise limits apply
only to noise currents induced onto the ac power lines in finished products. European Telecommunication Standard
Instructions (ETSI) are an exception, applying CE requirements to dc supplies with cables over three meters long.
Although not required to do so by agency standards, some system designers apply the conducted emissions
requirements to subassemblies within the product to reduce internal interference between subsystems and to
reduce the difficulty of meeting overall system requirements.
To meet these requirements, external filtering of the power module is often required. The filter module is a filter that
has been optimized for use with F and J series power modules. When used in conjunction with the recommended
external components and layout, it will significantly reduce the conducted differential and common-mode noise
returned to the power source. CISPR and FCC class B requirements can be met by using the filter as described in
the following sections.
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
