2 The maximum DC current is the value at which the inductance falls to 75% of its nominal value or when its temperature rise reaches
40°C, whichever is sooner.
3 Including self heating of the device.
4 Representative samples of the product were subjected to the conditioning described in IPC/JEDEC J-STD-020D and passed electrical
testing, package coplanarity and visual inspection which revealed no external cracks or changes in package body fl atness.

Custom inductance values available
The 2700 series is a range of ultra-low profi le,
surface-mount power inductors. They are designed
for use in power applications with restricted
height, such as handheld devices, DC-DC
converters and notebook computers. The products
are supplied in tape and reel for high-volume,
automated surface-mount assembly.
