SMD Inductors(Coils)
For Power Line(Wound)
VLP Series VLP4612
FEATURES
• This is an SMD power inductor for power supplies that has an
open magnetic path construction based on a low-height drum
core (upright).
• User terminals are contact-formed on the bottom of the drum
core using copper (finished with tin plating).
• It uses crosswise windings and supports large currents.
• It is lead-free compatible.
• With several variations in drum core height, users can choose
the perfect product for their application.
APPLICATIONS
• LCD modules
• Cellular phones
• Hard disk drives

Rated current:The rated current is the smaller of the values given based on the rate of inductance change (10% decrease from the initial value) or the
temperature rise (temperature rise of 40°C caused by the heat generated by the product itself). Please note that the current applied must be
DC.
