1.3
Inductive components are used for magnetic energy storage in all kinds of switch-mode power sup-
plies and DC/DC converters. For example, the SIMID 1812 product range is used in low-power step-
up converters in automobile electronics and in battery-powered equipment. They can be subjected
for short periods to currents which are the quadruple of their current rating without any saturation
effects occurring.
1.4
For broadband interference suppression, current-compensated chokes with ring cores or D cores
and powder core chokes are especially suitable.
Apart from use as filters in mains and other power supply lines, such chokes are important for data
lines as used in telecommunications engineering, e. g. in NTBAs (Network Termination Basic Ac-
cess Units, ISDN), in line cards in telephone exchanges (ISDN and analog) and in the fast-expand-
ing CAN bus application field (CAN = Controller Area Network) in automotive electronics.
Almost all the component families are approved in accordance with the main international stan-
dards. All chokes for low-frequency mains networks are dimensioned and tested in compliance with
the applicable EN and IEC standards.
Inductive components with particularly good RF characteristics are achieved by the use of ungapped
cores. The manufacturing methods developed by EPCOS lead to good reproducibility of the attenua-
tion characteristics and enable the production of high-quality components at a favorable price.

General Technical Information
Common-mode interference (asymmetrical interference):
– occurs between all lines in a cable and reference potential
– occurs mainly at high frequencies (from approximately 1 MHz upwards).
Differential-mode interference (symmetrical interference):
– occurs between two lines (L-L, L-N)
– occurs mainly at low frequencies (up to several hundred kHz).
