Description
The FLTR75V05 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 5 A. It provides high insertion loss throughout the frequency range regulated by the U.S. Federal Communi-
cations Commission (FCC) and the International Special Committee on Radio Interference (CISPR) for con-
ducted emissions.
The module is 25.4 mm long, 25.4 mm wide, and 10.2 mm high (1.0 in. x 1.0 in. x 0.4 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 con-
ducted 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 low-
profile 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 com-
mon-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. When used in conjunction with
the recommended external components and layout, the Lineage Power filter module will significantly reduce the
conducted differential and common-mode noise returned to the power source. CISPR and FCC class B require-
ments 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 abso-
lute 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.
