DC/DC Converters
TMH Series, 2 Watt
compliant
RoHS
Features Single-in-Line Package (SIP) Fully SMD-design Isolated Single and Dual Output I/O-Isolation `000 VDC High Efficiency up to 83 % Industry Standard Pinout 00% Burn-in (8 h) Lead free Design, RoHS compliant 3 Year Product Warranty
The TMH series are ultra miniature, isolated 2 Watt DC/DC-converters in a Singlein-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.
