The TMU 3 series consists of a set of isolated 3 Watt DC/DC converters with
unregulated outputs in a standard SIP-4 package. They are designed to offer a
compact low-cost alternative to regulated series with no concession on quality
and lifetime. They feature a continuous short circuit protection circuit, I/O-isolation of 1500 VDC and an operating temperature range from –40°C to 75°C
without derating. The compact dimensions of these converters make them an
ideal solution for many space critical applications in communication equipment,
instrumentation and industrial electronics.
