Panasonic ETQP4L-WFC and ETQP4L-XFC Power Inductors provide low loss with 0.7mΩ to 1.56mΩ DC resistance (DCR) and ±5% to ±10% DCR tolerance. These high-power inductors offer a 21A to 28A rated current and are suitable for high-frequency circuits up to 1MHz. The power choke coils have an 11.5mm x 10mm x 4mm package size, shielded construction, and low buzz noise due to the gapless structure. Panasonic ETQP4L-WFC and ETQP4L-XFC Power Inductors are ideal for use in notebook and desktop PC power supply modules as well as in servers, routers, and DC/DC converters for driving CPUs.
