• All specifications are subject to change without notice.

VLM Series  VLM10555-2

• Low loss and large current capability design.

• High magnetic shield construction should actualize high resolu-

tion for EMC protection.

• Available for automatic mounting in tape and real package.

Note book type and mobile computers, amusement equipment, 

DVD players, VRMs, plasma displays, etc.

∗

Rated current: Value obtained when current flows and the temperature has risen to 40°C or when DC current flows and the nominal value of inductance 

has fallen by 30%, whichever is smaller.
