DC/DC Converters THD 10 Series, 10 Watt CB Scheme UL 60950-1 Features Very high power density in DIP24 package Wide 2:1 input range Very high efcfi iency up to 87% I/O isolation 1500V Input filter to meet EN 55022, class A without ext. components Low ripple and noise Continuous short circuit protection Operating temp. range 40C to +71C 3year product warranty The THD-10 series is a range of isolated high performance 10W DC/DC converters in a low prole Dfi IL-24 package with standard industry pin-out. Other features of this product are built-in overvoltage protection and internal EMI-lfi ter to meet EN 55022, class A. Full SMD-design with exclusive use of ceramic capacitors guaran- tees a high reliability and long product lifetime. Typical applications for these con- verters are industrial electronics, instrumentation, data communication systems and battery operated equipment with limited space available on the PCB.
