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
