The THD-12 series is a range of high performance, isolated 12W dc/dc convert-
ers. They come in a low profile, DIP-24 package with standard industry pin-out.
Overload and overvoltage protection as well as remote On/Off are included as
standard. Built-in filters for both input and output minimizes the need of external
filtering. Full SMD-design with exclusive use of ceramic capacitors guarantees a
high reliability and long product lifetime. Typical applications for these converters
are industrial electronics, instrumentation, data communication systems and battery
operated equipment with limited space available on the PCB.
