Coilcraft’s new XGL4030 Series of high-performance, moulded power inductors offer up to 40% lower DCR than the previous inductors as well as extremely low AC losses, resulting in the best overall efficiency over a wide range of AC ripple current.

They are well suited for DC/DC converters with switching frequencies ranging from hundreds of kHz to 5 MHz and above.

The XGL4030 features an expanded inductance range, including 18 values from 0.13 to 12.0µH, with current ratings up to 26.5A and soft saturation characteristics. It also offers a 30% increase in Irms self-heating current, allowing the XGL4030 to operate much cooler than previous-generation components.

XGL4030 Series inductors are qualified to AEC-Q200 Grade 1 standards (-40 to +125°C ambient) with a maximum part operating temperature of +165°C and exhibit no thermal aging issues, 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 minimizes audible buzzing.

As with all Coilcraft parts, free evaluation samples of the XGL4030 Series are available online.
