In a fully encapsulated single-in-line through-hole format occupying less than 1.17 cm 2 footprint, MEF1 converters are available with either 1 kVDC or 3 kVDC 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 +85C without derating. Certification to the internationally recognized safety standard UL60950 is pending.
