Coilcraft
has released two high-current, molded power inductors that offer unique
termination options. Both inductors come in composite construction, which
results in soft saturation characteristics, allowing inductors to withstand
high-current spikes.

First, take the XTL7030
Series inductors, which offer side-metal terminations for automated optical
inspection (AOI) of the component during the solder reflow process. The
inductance values range from 10 µH to 47 µH, which is significantly higher than
competing products in the same size.

The
XTL7030 inductors offer current handling capability of up to 5.3 A and very low
AC/DC losses to ensure power efficiency. And they are qualified to the AEC-Q200
Grade 1 standards while supporting ambient temperatures ranging from –40°C to 125°C.
That makes them highly suitable for automotive and other harsh-environment
applications.

The
XTL7030 inductors measure just 7.1 mm2, come in a maximum height of 3.2 mm, feature
RoHS-compliant tin-silver over copper terminations, and are halogen-free. On the
other hand, Coilcraft’s XAR7030 Series inductors measure 8.5 mm2 and
feature terminals that elevate the inductor body 1.5 mm from the PCB surface.

Its
off-the-board construction allows power-management IC packages like QFN to be
mounted beneath the inductor in a 3D-packaging arrangement. And that
significantly reduces the board space.

The inductance values in XAR7030 Series range
from 0.16 µH to 10 µH. Next, the inductors offer direct current resistance
(DCR) as low as 1.26 mΩ. The XAR7030 inductors boast RoHS-compliant matte tin
over nickel over phos bronze terminations and are halogen-free.
