Coilcraft has expanded its market-proven XEL Family of high-performance, moulded power inductors to include three new higher-voltage series: the XEL401xV, XEL4020V and XEL4030V. All three offer operating voltage ratings of 120V, 50% higher than the standard versions. 

They also offer low DC resistance and ultra-low AC losses for greater power converter efficiency at high frequencies (2 to 5+ MHz) and high ripple current.

XEL40xxV Family inductors measure just four by four millimetres with a maximum height of 3.2mm and feature a rugged, composite construction that provides magnetic shielding and minimises audible buzzing. The XEL401xV Series is available in six inductance values from 92 to 780nH, with current ratings up to 24.0A. 

The XEL4020V Series has ten values from 0.08 to 2.2µH and current ratings up to 33.2A. The XEL4030V Series is offered in 13 values from 0.10 to 6.8µH and current ratings up to 30.0A. 

All models offer soft saturation characteristics to withstand high current spikes. They are qualified to AEC-Q200 Grade 1 (-40 to +125°C) standards and exhibit no thermal ageing issues, making them ideal for automotive and other harsh-environment applications. They also feature RoHS-compliant, tin-silver-over-copper terminations and are halogen free.
