Large Current Low Loss Metal Material Power Inductor WPN-V Series

Overview

WPN-V series SMD power inductors use Fe base metal material core winding by flat copper wires of 180 centigrade degree and coat with magnetic-resin as shielded construction. It provides lower RDC compared with WPN-H series, and especially is applicable for portable equipments requiring large power, such as smart phone, tablet PC.

Features

  • Fe base metal material has higher saturation characteristic than ferrite material and provides larger saturation current. 
  • The soldering in the side, lower DCR decreases power loss compares with WPN-H series. 
  • Magnetic-resin shielded construction reduces leakage flux and Electro Magnetic Interference (EMI) 
  • Metallization on metal core results in excellent shock resistance and damage-free durability 
  • Small and slim take up less PCB real estate 
  • Automatic production ensures high quality and consistency

Applications

  • Smart phone 
  • Tablet PC, notebook, desktop computer, server 
  • Blue -ray disc recorder, set top box 
  • Portable gaming device, personal navigation system, personal multimedia device
