VLP4612T-3R3MR85

(1/1) SMD Inductors(Coils) For Power Line(Wound) Conformity to RoHS Directive VLP Series VLP4612 SHAPES AND DIMENSIONS On the side at which the winding starts 3.0±0.20 Inductance marking 4.6±0.20 1.2max. 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 Dimensions in mm RECOMMENDED PC BOARD PATTERN ø3 .5 1.2 Dimensions in mm ELECTRICAL CHARACTERISTICS Part No. Inductance (µH) VLP4612T-1R0M1R5 VLP4612T-1R8M1R3 VLP4612T-2R5M1R1 VLP4612T-3R3MR85 VLP4612T-4R7MR72 VLP4612T-6R8MR67 VLP4612T-100MR52 VLP4612T-150MR42 VLP4612T-220MR34 1.0 1.8 2.5 3.3 4.7 6.8 10.0 15.0 22.0 ∗ Inductance tolerance (%) ±20% ±20% ±20% ±20% ±20% ±20% ±20% ±20% ±20% Test frequency (kHz) 100 100 100 100 100 100 100 100 100 DC resistance (Ω)max. 0.11 0.14 0.17 0.26 0.28 0.38 0.62 0.96 1.42 Rated current(A)∗ Based on inductance change 2.30 max. 1.70 max. 1.40 max. 0.90 max. 0.88 max. 0.77 max. 0.59 max. 0.45 max. 0.39 max.

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.
