DC/DC Converter
TEF Series 3 Watt
The TEF-series is a family of isolated dc/dc-converters that offers a
cost effective solution for applications requiring miniature size and
high performance features. SMT-design with exclusive use of ce-
ramic capacitors guarantees a very high reliability with an MTBF of
over 1’000’000 hours. A highly automated production with 100%
parameter test ensures a high quality standard of this product.
