CME0303S3C Description

Short technical summary and product information.

The Murata CME0303S3C is a compact isolated DC-DC converter module from the CME series, delivering a single 3.3V output at 227mA with 750mW of output power. It operates from a nominal 3.3V input voltage with a range of 2.97V to 3.63V, and achieves a typical efficiency of 73% at full load.

 

This converter provides 3000VDC isolation (flash tested for 1 second) with an isolation resistance of 10 GΩ, making it suitable for applications requiring galvanic isolation. Output ripple and noise is typically 15mV p-p, with a maximum of 25mV p-p. The switching frequency is 135kHz.

 

The CME0303S3C is housed in a standard 4-SIP through-hole package measuring 11.5mm x 6.0mm x 7.5mm, compatible with industry-standard pinouts. It operates over a wide temperature range of -40°C to +85°C, and is designed for ITE (commercial) applications. The module includes short circuit protection options.
