VLF3010AT-1R5N1R2

(1/2) SMD Inductors(Coils) For Power Line(Wound, Magnetic Shielded) Conformity to RoHS Directive VLF Series VLF3010A FEATURES • These are compact inductors for power line measuring at L2.6× W2.8mm and 1mm in height, considerably smaller compared to inductors with comparable characteristics. • They feature low coil resistance, making them suitable for large currents (e.g. 0.7A at 0.24Ω). • They offer an excellent shielding effect. • The products do not contain lead and support lead-free soldering. • This product does not contain regulated substances that are slated to be included in RoHS. APPLICATIONS For mobile phones, hard disk drives and DSCs. RECOMMENDED PC BOARD PATTERN 4R7 2.6±0.2 1.2 SHAPES AND DIMENSIONS 2.1 3.4 2.8±0.2 Dimensions in mm 1.0max.
