WPN252010U

Product Introduction

Sunlord WPN252010U is a wire-wound SMD power inductor from the WPN series in 252010 (2.5×2.0×1.0mm), built on a Fe-based metal-alloy core for high saturation current and low DCR. 0.16μH~4.7μH operates from -40°C~+125°C (including self-heating) in smartphone, set-top-box, VR/AR, notebook, desktop, server and portable-console DC-DC converters.

Core Advantages

• Wire Wound SMD Power Inductors (WPN): 252010 (2.5×2.0×1.0 mm) U-type low DCR, 0.16–4.7 μH, Isat up to 12 A — Fe-based metal-alloy core — high saturation current and low DCR.
• Low DCR, high current: DCR 0.020Ω~0.240Ω; saturation current up to 12.0A — high DC-bias performance in a 252010 body.
• Supply: YQM ELECTRONICS holds Sunlord stock with fast samples, datasheets and FAE support for volume programs.

Applications

FAQ

Q: What does an Fe-based metal-alloy core give me?

A: Metal-alloy powder cores sustain far higher DC bias before saturation than ferrite, so a small WPN part can carry a large current with low DCR and low loss.

Q: How are Isat / Irms defined?

A: Isat is the current at roughly 30 % inductance drop; Irms is the current at ΔT = 40 °C, tested at 1 MHz / 1 V.
