DC/DC Converter THD 12 Series 12 Watt Features Highest Power Density: 12W in DIL-24 Package! Pending Wide 2:1 Input Range Very high Efficiency up to 88% I/O-Isolation 1500V Input Filter meets EN55022A without ext. Components Remote on/off Low Ripple and Noise Continuous Short Circuit Protection Operating Temp. Range -40C to +75C (with Derating) 3 Year Product Warranty The THD-12 series is a range of high performance, isolated 12W DC/ DC converters. They come in a low profile, DIL-24 package with standard industry pin-out. Overload and overvoltage protection as well as remote on/off are included as standard. Built-in filters for both input and output minimizes the need of external filtering. Full SMD-design with exclusive use of ceramic capacitors guarantees a high reliability and long product lifetime. Typical applications for these converters are industrial electronics, instrumentation, data communication systems and battery operated equipment with limited space available on the PCB.
