IEC-inlet filters
Time-to-Market
The most important reasons for choosing a catalog
product lies in the rapid availability and the
associated safety acceptances. Filter circuits with
discrete components at the mains input can, of
course, be built but do not necessarily represent the
best solution particularly in products with a
compressed development cycle such as in the
PC field.
Standard IEC connector filters are a practical single-
source solution. Thanks to their compact
dimensions and supplementary options they offer
numerous advantages to the user.
The following summary provides a simple and rapid
means for making a filter pre-selection. Detailed
information concerning the individual filters is given
on the subsequent pages. Variants having an earth
choke are designated by the letter “E” (e.g. FN
393E) and filters for medical applications by the
letter “B” (e.g. FN 385B).
together with the more important remarks shown at the right. Detailed technical information concerning each filter family can be found on the following pages.

It is easy to determine which family of filters would be suitable for your particular application on the basis of the current range and insertion loss values

General technical information
Insertion loss
The insertion loss characteristics of the filters are
measured in accordance with the CISPR 17
standard. Two test conditions are specified in
Section 4.2 of the CISPR 17 standard namely input
and output impedances of 50/50Ω and 0.1/100Ω. In
general, the IEC inlet filters perform the same in the
face of differential interference as in the 50Ω
insertion loss test. In order to show the
performance under realistic conditions, Schaffner
also shows the attenuation curves obtained from
the 0.1/100Ω test which are more meaningful for
common mode interference. The inductance of the
chokes used in the filters can change under load
because of a saturation effect which can also affect
the insertion loss.
Voltage ratings
The use of capacitors in accordance with
IEC 384-14 means that Schaffner filters can be
operated at voltages up to 10% over the nominal
voltage rating.
Leakage current
The figure quoted for the leakage current to ground
indicates the maximum value per phase at
230V/50Hz.

Switches
The switches used in the filters listed in this catalog
have an in-rush current rating of up to 51A as
defined in UL 1045, TV3.
Flammability classification
All the filters in this catalog comply with the
requirements of UL 94V2 or UL 94V0.
Climatic classification
The filters made by Schaffner comply with the
climatic classification 25/085/21 according to DIN
IEC 68 Part 1 (ambient temperature -25ºC to +85ºC).
