At the Applied Power Electronics Conference (APEC 2016) in California, USA, Coilcraft has introduced a series of low-loss power inductors. The XEL40xx series is offered with lower inductance values that have been fully optimised for high frequency applications. They also offer extremely low DCR down to 2.5mΩ and ultra-low AC losses, resulting in the highest efficiency across a range of frequencies from 2 to over 5MHz.
The XEL40xx series are offered with current ratings as high as 28.5A and their soft saturation characteristics can withstand high current spikes.
XEL40xx series inductors measure just 4.0mm square with maximum heights as low as 1.2mm, making them suited for IoT and portable device applications. They feature RoHS compliant tin-silver over copper terminations and are halogen free. The XEL4014 and XEL4020 models are qualified to AEC-Q200 Grade 1 standards (-40 to +125°C ambient), making them suitable for automotive and other harsh-environment applications.
As with all Coilcraft parts, free evaluation samples of the XEL40xx series are available online.
