Coilcraft’s new XGL4030 Series of high-performance, moulded power inductors provide up to 40% lower DCR than their past best-in-class inductors as well as notably low AC losses, following in the best overall efficiency over a broad range of AC ripple current. They are excellent for DC-DC converters with switching frequencies varying from hundreds of kHz to 5MHz and above.
The new series provides an expanded inductance range, including 18 values from 0.13 to 12µH, with current ratings up to 26.5A and soft saturation characteristics. It also provides a 30% increase in Irms self-heating current, enabling the series to run far cooler than previous-generation components.
The series inductors are qualified to AEC-Q200 Grade 1 standards (-40C to +125C ambient) with a maximum part operating temperature of +165C and exhibit no thermal ageing issues, making them ideal for automotive and other harsh-environment applications. The devices feature RoHS-compliant, tin-silver-over-copper terminations and are halogen-free. Their composite construction also minimises audible buzzing.
