Flyback Transformers with Grounded Core and Reinforced Insulation

The new MID-OLRM extended rail RM8 transformer series for offline applications from Wurth Electronics Midcom is now available.

Available with single or dual 5V or 12V outputs, these flyback transformers are built with grounded cores for improved EMI performance, small footprint, and reinforced insulation.

The 7508112110, 7508112349, 750811618, and 7508116316 transformers are best suited for white goods, industrial controls, metering, LED lighting, offline flyback power supplies, space-constrained power supplies, and smart adapter applications.

“For the past 30 years, the RM packages have required flying leads to meet reinforced insulation and creepage and clearance distances. We decided to change this by adding an extended rail to the existing RM8 package; eliminating the need to have flying leads,” explained Swaroop Vaidyanath, Product Marketing Engineer at Wurth Electronics Midcom.

This package also meets the stringent IEC61558-2-16 standard with reinforced insulation,” Vaidyanath concluded.
