High-Permeability, Nanocrystalline Common-Mode Chokes

Pulse Electronics Power BU adds a new series of high permeability, nanocrystalline products to its lineup of common mode chokes – the PA441xNL series. The PA441xNL series is comprised of two THT common mode chokes (PA4415NL and PA4416NL) that are well-suited for engineers designing their own EMI filter for ac-dc, dc-dc or dc-ac power converters.

Notable features and benefits include very high and stable impedance through broad frequency and temperature ranges, a 43.0 x 26.0 mm max footprint and nanocrystalline core for compact design. Given its capabilities and RoHS compliance, the new PA441xNL series is expected to be used in applications like power supplies, solar inverters and dc-dc converters, motor drives, industrial controls, electric vehicle charging, smart grid and power generation.

“These new common mode chokes provide over 4x the impedance in a given form factor compared to traditional ferrite core products, allowing superior EMI performance and high power density,” stated John Gallagher, Staff Field Applications Engineer at Pulse Power BU.
