Pulse expands its range of high current, surface mount common mode chokes with the introduction of the PH9407/08 series. Using Pulse’s round wire coil winding technology, horizontally mounted in a planar core, these new series offer one of the lowest profiles, highest current, surface mount packages currently in the market. Two platforms have been developed, the ER19 (24.9 x 21.6 x 16.9 mm) and the ER25 (30.5 x 27 x 18 mm) which offer inductances from 120 µH to 1450 µH, with currents up to 39A.
“With increasing power requirements, need for high density low EMI systems, and the on-going conversion of high-power assemblies from through-hole to surface mount, the PH9407/08 is ideally suited for next generation designs. The recently launched PA514x provides a footprint optimized solution with the implementation of our round wire coil technology in the EP core shape. This new series is the planarized version of that concept, reducing the height by up to 8.5mm.”

The horizontally mounted construction makes this product-line well suited for high-performance, high-reliability applications in data communications, computing, and industrial markets where available height is at a premium. Such a feature has also made this series attractive to the automotive market. Therefore, Pulse has started the development of an IATF PM940x equivalent for applications that require AEC-Q200 qualification and PPAP documentation.
