The THD-10 series is a range of isolated high performance 10W DC/DC converters
in a low profile DIL-24 package with standard industry pin-out. Other features of
this product are built-in overvoltage protection and internal EMI-filter to meet EN
55022, class A. 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.
