Product Overview
The CMLW4030S Series is a wire-wound SMD power inductor featuring magnetic-resin shielding for ultra-low buzz noise. Its metallization on the ferrite core ensures 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. Ideal for LED lighting, mobile devices, flat-screen TVs, notebooks, servers, automotive systems, and telecomm base stations.

Notes:
1. All test data is referenced to 20C ambient.
2. Rated current: Isat or Irms, whichever is smaller.
3. Isat: DC current at which the inductance drops approximately 30% from its value without current.
4. Irms: DC current that causes the temperature rise (T =40C) from 20C ambient.
Standard Packing Quantity: 2000 pcs/reel.
