MEF1 Series 1 Watt Regulated DC-DC Converters | Murata PS

The MEF1 series of 1 Watt regulated DC-DC converters is suitable for use in industrial, automation, and instrumentation applications. These tightly regulated single output converters, rated to better than 1% of nominal output voltage, are packaged in a fully encapsulated single-in-line through-hole format occupying less than 1.17 cm squared footprint.

The MEF1 converters are available with either 1kVDC or 3kVDC input to output isolation, the latter model having an enhanced immunity to voltage transients. Output voltage options are 3.3 or 5.0 VDC, with input voltages covering the popular nominal inputs from 3.3 to 24 VDC.

Compared to previously available models, the MEF1 offers a 13% improvement in energy efficiency. Both the 3.3 VDC input and 3.3 VDC output options can operate over the full industrial temperature range of -40 to +85°C without derating.
