High-Reliability High-Inductance Common & Differential Mode Inductors for Power Line Noise Filtering

Product Details

The LFUR17A Series is a high-performance line of Common Mode Inductors and Differential Mode Suppression Inductors, designed to deliver exceptional noise attenuation for modern power electronics. As part of advanced EMI Filters, RFI Filters, and High Inductance Power Line Noise Filters, this series provides optimized inductance, low DCR, and reliable performance in compact PCB-mount designs.

Engineered to meet UL insulation standards and US lighting safety requirements, the LFUR17A series is ideal for high-efficiency SMPS, LED drivers, CCFL backlighting, offline switching power systems, and power tools. These inductors offer excellent differential-mode inductance with low resistance, enabling stable operation under noisy environments and fluctuating ground conditions.

With inductance values ranging from 3.3 mH to 100 mH, DCR as low as 0.21 Ω, and current ratings up to 2.5 A, the LFUR17A series ensures robust EMI/RFI suppression while maintaining compact dimensions suitable for dense PCB layouts.
