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 inductors of equal size

 Takes up less PCB real estate and save more power

APPLICATIONS

 Smart phone, smart TV, set top box, notebook

 Car navigation systems, telecomm base stations

 VR, AR

 LED lighting
