The TES-3 series is a family of high performance 3W dc-dc converter modules
featuring wide 2:1 input voltage ranges. The 15 models come in a low profile
SMD package with dimensions of 32.3 x 14.8 x 10.2 mm. A high efficiency allows
an operating temperature range of –40°C to +85°C at full load.
This product is qualified for soldering in a high temperature lead-free reflow solder
process. Typical applications for the converters are battery operated equipment,
instrumentation, communication and industrial electronics, everywhere where an
isolated, tightly regulated voltage is required.
