Integrated Passive Components
Balanced Line EMI Chip
BLC
The Syfer Balanced Line Chip is a 3 terminal EMI chip device. The
revolutionary design provides simultaneous line-to-line and line-to-
ground filtering, using a single ceramic chip. In this way, differential
and common mode filtering are provided in one device. Capable of
replacing 2 or more conventional devices, it is ideal for balanced lines,
twisted pairs and dc motors, in automotive, audio, sensor and other
applications.
These filters can prove invaluable in meeting stringent EMC demands
particularly in automotive applications.
