Wire Wound SMD Power Inductors – WPN Series
Operating temperature range : -40℃~+125℃ (Including self-heating)
FEATURES
⚫
⚫
⚫
⚫
⚫
Fe base metal material core provides large saturation current
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)
Low DCR decreases power loss, small and slim take up less PCB real estate
Automatic production ensures high quality and consistency
APPLICATIONS
⚫
Smart phone, set top box, VR, AR
⚫
Notebooks, desktop computers, servers
⚫
Portable gaming devices, personal navigation systems, personal multimedia devices

※1: All test data is referenced to 20°C ambient;
※2: Rated current: Isat or Irms, whichever is smaller;
※3: For WPN2016 & WPN2520 size inductors, absolute maximum voltage: DC 25V; For WPN30 & WPN40 size inductors,
absolute maximum voltage: DC 40V;
※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.
※WPN-HS series is processed with surface coating technology, coated by the resin of high voltage insulation level coating
on the core surface evenly by automatic equipment, to improve the voltage insulation and corrosion resistance of the core.
