DC/DC Converter
TES 3 Series 3 Watt
The TES 3 converter series is intended for all applications where PCB’s are
assembled on an automated SMD production line. The smaller size DIL-package and the light weight allows easy handling by pick-and-place machines.
With their small footprint these converters are the state-of-the-art solution for all
on-board power applications demanding an isolated and regulated output
voltage.
