CMLW4018S Series
Wire Wound SMD Power Inductor
Pb
◆ Features
1、Magnetic-resin shielded construction reduces
buzz noise to ultra-low levels;
2、Metallization on ferrite core results in excellent
shock resistance and damage-free durability;
3、Closed magnetic circuit design reduces leakage
flux and Electro Magnetic Interference (EMI);
4、30% higher current rating than conventional
inductors of equal size;
5、Take up less PCB real estate and save more
power。
◆ Applications
◆ Lead Free Part Numbering
1、LED Lighting;
2、Mobile devices with multifunction such as
adding color TV and camera;
3、Flat-screen TVs, blue-ray disc recorders,
set top boxes;
4、Notebooks, desktop computers, servers,
graphic cards;
5、Portable gaming devices, personal navigation
systems, personal multimedia devices;
6、Automotive systems

◆ Note
:
:
:
:
1 All test data is referenced to 20°C 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 =40°C) from 20°C ambient.
