STANDARD PARTS SELECTION GUIDE
TYPE LLB2520
Part Numbering
* Rated DC current is that which the inductance decreases 10% by the excitation
DC current or which the temperature rises 20C by excitation DC current, whichever is lower.
Note: Add P2 to part number for tape and reel.
Recommended Solder Pad Layout
The LLB2520 Series is a miniature wirewound ferrite core chip
inductor in a 1008 footprint. It is especially designed to have
low DC resistance and high current handling capability. Its use
is ideal for the decoupling inductor in computers, consumer
electronics and portable electronics equipment.
