VLF3010AT-100MR49 TDK

4R7 (1/2) Conformity to RoHS Directive SMD Inductors(Coils) For Power Line(Wound, Magnetic Shielded) 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 0.24 ). They offer an excellent shielding effect. The products do not contain lead and support lead-free solder- ing. This product does not contain regulated substances that are slated to be included in RoHS. APPLICATIONS For mobile phones, hard disk drives and DSCs. SHAPES AND DIMENSIONS RECOMMENDED PC BOARD PATTERN 2.1 3.4 Dimensions in mm 2.80.2 1.0max.
