DC/DC Converters THD 12 Series, 12 Watt Features High power density DIP-24 metal package Wide 2:1 input range Very high efficiency up to 88% I/O isolation 1500V Input filter to meet EN 55022, class A Remote On/Off Under voltage lock-out circuit Shielded metal case with insulated Baseplate Continuous short-circuit protection Operating temp. range -40C to +85C (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, DIP-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.
