Premier Magnetics Drum Cores for EMI Filtering and Switch Mode Power Supplies

摘要

Premier Magnetics has introduced its new line of low-cost, high-performance drum core inductors designed for EMI filtering and switch mode power supply applications. With a product offering of over two dozen models with inductance values from 100 to 10,000 μH, the new PM-R series boasts low dc resistance (DCR), providing low temperature rise at high peak currents. Their combination of high peak current and high self-resonant frequency (SRF) make the PM-R Series inductors an ideal drop-in replacement for lower-performing drum core devices. And in applications where the devices' maximum height of 10.0 to 11.5 mm is acceptable, the PM-R Series offers a cost-effective alternative to surface-mount inductors.
