CMLW4018S Series Wire Wound SMD Power Inductor
The CMLW4018S Series features magnetic-resin shielded construction for ultra-low buzz noise and a metallization on ferrite core for excellent shock resistance. 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 space and power. They are ideal for LED lighting, mobile devices, flat-screen TVs, computers, servers, gaming devices, automotive systems, and telecomm base stations.

Notes
- All test data is referenced to 20C ambient.
- Rated current is the smaller of Isat or Irms.
- Isat: DC current at which inductance drops approximately 30% from its value without current.
- Irms: DC current that causes a temperature rise (T =40C) from 20C ambient.
