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.

Pulse Electronics continues the expansion of our composite core power inductor products adding four new platform sizes. These new products offer extremely high energy storage density 1300uJ/cm3, current ratings in excess of 39Apk and range in size from 4.3 x 4.3 up to 16.8 x 15.8.  Available in both commercial grade (-40C to 130C) and automotive grade (-55C to 155C) these products are ideally suited for any high performance applications in the communications, computing, industrial, and automotive market segments. Composite core inductors offer superior performance over similar molded powder inductors due to the high density core materials and low loss winding structure and retain the desired soft saturation characteristics.

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. 

Pulse Electronics is excited to introduce a new series of automotive grade, molded power inductors.  The PM434X series is ideal for high current, non-isolated DC/DC converters and voltage regulators.  This new inductor series expands on our existing commercial grade platforms by offering a fully certified IATF alternative offering the same superior electrical performance. It includes PM4340, PM4341, PM4342, PM4343, PM4344 & PM4345 offering 6 sizes with footprints spanning from 17x17mm down to 6x6mm and a low 2.0mm minimum profile.  These products are suitable for a wide range of automotive applications including seating, safety, lighting, entertainment and any other applications limited to 130C maximum temperature.

The PA/PM540x and PA/PM544x series is our newest line of Molded Power inductors. Designed for high efficiency applications in industrial, communications, computing, and automotive markets. These platforms have low power loss, excellent shielding and can handle high transient current spikes.Ranging in size from 3.7x3.4mm to 14x12.8mm they add to Pulse's existing molded inductor platforms. These new series of parts are available in both commercial grade (PA540x) and automotive grade (PM540x). Production lead time is approximately 12-14 weeks, and samples are available upon request. 

Automotive Grade Reinforced Insulation EP7 Platform

Pulse Electronics has released an automotive grade IATF certified version of our popular PH9185 series of high isolation voltage transformers.The PM2190.XXXNL series is suitable for a wide range of low power automotive applications where high voltage safety isolation is critical such as Battery Management Systems (BMS) and communication modules.

Pulse Electronics Power BU announces the release of the new PA4470.XXXNL High Frequency Wire Wound Transformers.  Designed to deliver high reliability and performance, the PA4470.XXXNL is a power transformer in a continuous mode flyback

Pulse Electronics Power BU introduces the new PM220X Series SMT Inductors.  Designed for automotive and industrial applications, the PM220X Series offers the same quality performance as the recently released PA500X series for commercial applications with the addition of an elevated operating temperature rating up to 155°C.

Pulse Electronics Power BU introduces the new PA4339.XXXNLT Small Form Factor Common Mode Choke Series for switch mode power supplies. Designed in a low profile, the PA4339.XXXNLT series is the most compact power line common mode choke on the market today that is capable of handling currents up to 9Adc. The compact design allows for a higher impedance per unit volume when compared to other chokes.

Pulse Electronics Power released a new series of high current, low profile SMT inductors. Designed with the highest energy storage density of any inductor on the market, the inductors have High Current >40Apk) and Low Profile (2.1mm to 5.0mm) features. They offer soft saturation, with no thermal aging and fit industry standard footprints.
