DC/DC Converters THD 12 Series, 12 Watt RoHS compliant Features ◆ Highest Power Density: 12W in DIL-24 Package! ◆ ◆ ◆ ◆ Wide 2:1 Input Range Very high Efficiency up to 88% I/O-Isolation 1500V Input Filter meets EN 55022A without ext. Components ◆ Remote On/Off ◆ Shielded Metal Case with insulated Baseplate ◆ Continuous Short-Circuit Protection ◆ Operating Temp. Range -40°C to +85°C (with Derating) ◆ Lead free Design, RoHS compliant ◆ 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.
