CMLW252010S 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
