Common-mode line filters for SMPS replace discontinued units

The PMCU Series of common mode line filters is designed for switching power supply applications. Offered in both standard winding (for higher efficiency) and sectional winding (for improved high-frequency performance), the updated PMCU offerings have been expanded to include a direct cross for over three dozen PLA10ANxxx and PLA10ASxxx EMIFIL series components recently discontinued by Murata Manufacturing Co., Ltd.

The devices comprising Premier Magnetics’ PMCU line are low-profile, vertical coil inductors with a wide operating temperature range (-40 to 80°C) and the isolation between windings is 2,000 Vrms. Tabled data on these filters can be found at http://www.premiermag.com/pdf/pmcu.pdf including the complete cross reference list. The devices are offered with current ratings from 0.3 to 2.0 A with rated voltage of 250 Vac, 50/60 Hz.

“Murata’s decision to discontinue these common mode line filters have left many manufacturers in a difficult position,” said Jim Earley, President of Premier Magnetics. “We have responded by providing a complete series of compatible devices.”
