Product Overview
The CMLW252012S Series is a wire-wound SMD power inductor featuring magnetic-resin shielded construction for ultra-low buzz noise. Its metallization on the ferrite core provides excellent shock resistance and durability. The closed magnetic circuit design minimizes leakage flux and EMI. These inductors offer a 30% higher current rating than conventional inductors of equal size, saving PCB real estate and power. They are suitable for a wide range of applications including LED lighting, mobile devices, flat-screen TVs, computers, gaming devices, automotive systems, and telecommunication base stations.

Notes:
- All test data is referenced to 20C ambient.
- Rated current: Isat or Irms, whichever is smaller.
- Isat: DC current at which the inductance drops approximate 30% from its value without current.
- Irms: DC current that causes the temperature rise (T =40C) from 20C ambient.
Operating Conditions:
- Operating temperature range (Including self-heating): -40 ~ +125
- Storage temperature range (packaging conditions): -10~+40 and RH 70% (Max.)
