Wire Wound SMD Power Inductors – SWPA Series
Operating temperature range: -40℃~+125℃ (Including self-heating)
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 nductors of equal size
Takes up less PCB real estate and save more power
APPLICATIONS
