Ferrite Core Wire Wound SMD Power Inductor Cybermax CMLW4018S220MST with Low EMI and Ultra Low Buzz Noise
Product Overview
The CMLW4018S Series is a Wire Wound SMD Power Inductor featuring magnetic-resin shielded construction for ultra-low buzz noise. Its metallization on ferrite core ensures excellent shock resistance and durability, while 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.

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 approximate 30% from its value without current.
4. Irms: DC current that causes the temperature rise (T =40C) from 20C ambient.
5. Operating temperature range (Including self-heating)-40 ~ +125.
6. Storage temperature range (packaging conditions): -10~+40 and RH 70% (Max.).
