DC/DC Converters
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 ran-
ge is –25°C to +71°C. This product series provdes a cost effective solution for many
industrial or consumer electronics applications.
