The THB-3 series is a range of high performance, regulated DC/DC converters in

a DIP-24 plastic package. A reinforced I/O-isolation system and a wide 2:1 input

voltage range make this product the best choice for many demanding applications

like transportation systems, industrial controls, medical equipments, instrumenta-

tions, everywhere where high basic-, supplementary- or reinforced insulation is

required to meet requested safety standards.

A high efﬁciency allows safe operation in a temperature range of –40°C to +85°C.

Other features of this product are over voltage protection and internal EMI-input

ﬁlter to meet EN 55022, class A without additional components. Full SMD-design

with exclusive use of ceramic capacitors ensure a very high reliability and a long

product lifetime.
