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.”
