The new XEL50xx family of high-performance, moulded power inductors from Coilcraft offer exceptionally low DC resistance and ultra-low AC losses, greatly improving power converter efficiency at high frequencies (2 to 5+ MHz) and high ripple current.
The use of high switching frequencies or high ripple current allows a corresponding lower inductance value, which results in a physically smaller part for the same electrical specs. XEL50xx inductors measure just 5,28 x 5,48 mm with a maximum height of 3,2 mm.
The product range is currently available in two models, the XEL5020 and XEL5030. A third model, the XEL5050, is expected late Q2 2018. The XEL5020 is available in six inductance values from 0,10 to 1,0 μH, with current ratings up to 39 A. The XEL5030 has ten values from 0,13 to 4,7 μH and current ratings up to 44 A. All models offer soft saturation characteristics to withstand high current spikes and have no thermal ageing issues.
The inductors are qualified to AEC-Q200 Grade 1 standards (-40°C to +125°C ambient) with a maximum part temperature of +165°C, making them suitable for automotive and other harsh-environment applications. They feature RoHS-compliant, tin-silver-over-copper terminations and are halogen free. Their composite construction also minimises audible buzzing.
