DC/DC Conver ter
THP 3 Series 3 Watt
The THP-3 series is a new range of high performance 3W DC/DC con-
verters in a low profile DIL-24 package with standard industr y pin-out.
The very high I/O-isolation system of these converters and input voltages
up to 160 VDC make this product the best choice for many demanding
applications in railroad and transportation systems, medical equipment,
instrumentation, everywhere where high basic-, supplementary- or rein-
forced insulation is requested to meet specific safety standards. A high
efficiency allows safe operation in a temperature range of –40°C to +75°C
at full load without derating. Full SMD-design with exclusive use of ce-
ramic capacitors ensure a ver y high reliability and a long product life-
time.
