Abstract

The present disclosure provides a coil assembly including a coil and an external electrode electrically connected to the coil. The coil may include a plurality of coil patterns. An end of the outermost coil pattern may include a gap filling part. The through via directly connected to the innermost coil pattern may further include a gap filling part.

Description

[0001] This application claims the benefit of priority of Korean Patent Applications No. 10-2017-0074202 and No. 10-2017-0143076 filed with the Korean Intellectual Property Office on June 13, 2017 and October 31, 2017, respectively, The disclosure of said Korean patent application is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to a coil assembly, and more particularly, to a film type power inductor. Background technique [0003] According to the recent development of portable wireless communication devices and wearable devices, components having high performance, slim thickness, and small size have been required. In particular, recent portable smartphones and wearable devices operate at higher frequencies, and need to stably supply power in the higher operating frequency range. Therefore, power inductors for suppressing rapid changes in current at power supply terminals have been required to be able to be used at...
