■Features

－The

miniature chip inductors is wound on a special ferrite core.

－VLH322515/322520/453226

are low DC resistance.

－VLH322520C/453226C/565047C

are low DC resistance, high

current capacity, and high impedance characteristics. They are

excellent for using as a choke coil in DC power supply circuits.
