DC/DC Converter

TEM 3 Series 3 Watt

The TEM 3 series is a range of isolated dc/dc converters in a
DIL-24 package. They offer tight output regulation and very low
output noise. Operating temperature range is –25 °C to +70°C.
This product series provides a cost effective solution for many
industrial or consumer electronics applications.
