New Common Mode Choke Series PA5140/41

PA5140_41 Video


Pulse Electronics expands its range of surface mount common mode chokes with the introduction of the PA5140/41 series. Using the fully automated round wire coil forming technology developed for its existing high current inductor product line, these new series offer the highest available current in a surface mount package. Two platforms have been developed, the 18x19x19mm EP18 and the 23x23x23mm EP22 which offer inductances from 110uH to 470uH, with currents up to 32A. These EP cores have been designed around the coil dimension to minimize the component size, offering a higher-density inductance/current solution. The high permeability ferrite material minimizes the number of turns (and therefore the DC resistance) resulting in a much higher current rating that other similarly sized common mode chokes.

High Power Planar Magnetics Design for Automotive Applications

The demand for electric vehicles, for both personal and commercial transportation, continues to grow and with this growth comes increased pressure on designers of on-board chargers (OBC) and DC/DC inverters to ensure the battery packs are efficiently utilized.  This reality, in turn, puts renewed focus on the power magnetic components that are used to provide isolation and voltage conversion throughout the vehicle.  

The need to ensure that these high power magnetics are optimized in terms of density, weight, efficiency and cost along with the increased usage of resonate mode switching topologies dictates the use of advanced 3D design techniques. It is no longer possible to create a viable design using 2D iterative equations. Pulse Electronics employs our expertise and vast design experience to provide leading edge power magnetics.
