Two new power inductors offer unique termination options
Coilcraft has introduced two new products to its line of high current, molded power inductors, both offering unique termination options.
The XTL7030 Series features side metal terminations for automated optical inspection (AOI) of the component during the solder reflow process. It offers inductance values from 10 to 47µH – significantly higher than products currently available from other manufacturers in the same size part. It also provides excellent current handling (up to 5.3A) and exceptionally low AC + DC power losses for greater efficiency.
The inductors measure just 7.1mm square, with a maximum height of 3.2mm. They feature RoHS compliant tin-silver over copper terminations and are halogen free. They are also qualified to AEC-Q200 Grade 1 standards (-40C to +125C 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 unique off-the-board construction allows standard power management IC packages (e.g., QFN/VQFN) to be mounted beneath the inductor in a 3D packaging arrangement, reducing overall board space. The series is available with inductance values ranging from 0.16 to 10µH. It also offers extremely low DCR – as low as 1.26mOhms. It features RoHS compliant matte tin over nickel over phos bronze terminations and is also halogen free.
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.
