CMLW4020S Series
Wire Wound SMD Power Inductor
◆
Features
Magnetic-resin shielded construction reduces
buzz noise to ultra-low levels
Metallization on ferrite core results in excellent
shock resistance and damage-free durability
Closed magnetic circuit design reduces leakage
flux and Electro Magnetic Interference (EMI)
30% higher current rating than conventional
inductors of equal size
Take up less PCB real estate and save more
power

Note
All test data is referenced to 20°C ambient;
Rated current: Isat or Irms, whichever is smaller;
Isat: DC current at which the inductance drops approximate 30% from its value without current;
Irms: DC current that causes the temperature rise ( T =40°C) from 20°C ambient.
