PRODUCT OVERVIEW
The 8400 series is a range of miniature, surface-
mount,
I-core
power inductors. They are designed
for use in power applications with restricted
PCB space and height, such as ExpressCard™
technology, handheld devices, DC-DC converters
and notebook computers. The products are
supplied in tape and reel for high-volume,
automated surface-mount assembly.
