The TMH series are ultra miniature, isolated 2 Watt DC/DC-converters in a Single-
in-Line package (SIP). Requiring only 1.5 cm2 board space they offer the ideal
solution in many space critical applications for board level power distribution. The
use of SMD-technology makes it possible to offer a product with high performance
at low cost.
