PA441xNL-common-mode-chokes

The PA441xNL series is our newest line of THT, high permeability, nanocrystalline common mode chokes.

The series currently contains two products, PA4415NL and PA4416NL, that were purpose built for customers engaged in EMI filter design for AC/DC, DC/DC or DC/AC power supplies.

“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.”
John Gallagher | Staff Field Applications Engineer

PA441xNL Key Features

PA441xNL series has been added to our existing family of common mode chokes. Both the PA4415NL and PA4416NL are RoHS compliant and deliver an exceptionally high level of impedance per unit volume, stable impedance across temperature range, compact design, and high quality, automated manufacturing.

  • Dielectric Strength: 1500Vrms
  • Inductance Range: 14 mH (at 8A) to 35mH (at 5A)
  • Height: 46.0 mm max
  • Footprint: 43.0 mm x 26.0 mm
  • Voltage Rating: 250 Vac Max, 1500 Vrms Hi-pot
  • Nanocrystalline Core
  • RoHS Compliant

PA441xNL Applications

The amorphous core within the PA441xNL series enables high impedance per volume, allowing designers to minimize board space while while maximizing common mode noise rejection.

These capabilities make the PA441XNL series ideally suited for the following applications:

  • AC/DC Power Supply
  • Solar
  • Motor Drives
  • Industrial Control
  • EV Charging
  • Smart Grid
  • Power Generation
