The THD-12WI series is a range of high performance, isolated 12W dc/dc converter

modules featuring ultra wide 4:1 input voltage ranges in a DIP-24 package with

industry-standard footprint. 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 capaci-

tors guarantees a high reliability and long product lifetime. Typical applications for

these converters are industrial electronics, instrumentation, data communication sys-

tems and battery operated equipment with limited space available on the PCB.
