The range offers inductance values from 10 to 47 µH – significantly higher than alternative products in the same size part. It also provides current handling up to 5.3 Amps and very low AC + DC power losses for greater efficiency.

 

XTL7030 inductors measure 7.1 mm square, with a maximum height of 3.2 mm. They feature RoHS compliant tin-silver over copper terminations and are halogen free. They are also qualified to AEC-Q200 Grade 1 standards (-40° to +125°C ambient), making them suitable for automotive and other harsh-environment applications.

 

The XAR7030 Series marks the first time raised inductors are available as standard, off-the-shelf products. They measure 8.5 mm square, with terminals that elevate the inductor body 1.5 mm from the printed circuit board surface. The off-the-board construction allows standard power management IC packages (e.g., QFN/VQFN) to be mounted beneath the inductor in a 3-D packaging arrangement, reducing overall board space. The XAR7030 is available with inductance values ranging from 0.16 to 10 µH. It also offers extremely low DCR – as low as 1.26 mOhms. It features RoHS compliant matte tin over nickel over phoshor bronze terminations and is also halogen free. Contact Coilcraft to discuss raised inductors in other sizes.

 

The composite construction of both products results in soft saturation characteristics, allowing them to withstand high current spikes. They exhibit no thermal ageing issues, and their construction also minimizes audible buzzing.
