Product Overview
The CMLW4020S Series is a wire-wound SMD power inductor featuring magnetic-resin shielding for ultra-low buzz noise and a metallized ferrite core for excellent shock resistance and durability. Its 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. Applications include LED lighting, mobile devices, flat-screen TVs, computers, servers, gaming devices, automotive systems, and telecommunication base stations.

Notes:
1. Operating temperature range (Including self-heating): -40 ~ +125.
2. Storage temperature range (packaging conditions): -10~+40 and RH 70% (Max.).
3. All test data is referenced to 20C ambient.
4. Rated current: Isat or Irms, whichever is smaller.
5. Isat: DC current at which the inductance drops approximate 30% from its value without current.
6. Irms: DC current that causes the temperature rise (T =40C) from 20C ambient.
7. Standard Packing Quantity: 3000 pcs/reel.
