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.
