The THN 30WI series is the latest generation of high performance DC/DC converter

modules with highest power density. The product achieves 30W output power while

it comes in a metal case with dimensions of only 1.0”x 1.0”x 0.4”.

All models have an ultra wide 4:1 input voltage range and precisely regulated

output voltages, even under no load conditions. Highest efﬁciency across full load

range makes this product very reliable and applicable in temperature ranges of up

to 85°C. With a low input current at minimal load and remote On/Off control these

converters are the ideal solution for battery-operated systems. Typical applications

are in mobile equipments, instrumentation, distributed power architectures in com-

munication and industrial electronics and everywhere where space on the PCB is

critical.
