WPN3012H

Product Introduction

Sunlord WPN3012H is a wire-wound SMD power inductor from the WPN series in 3012 (3.0×3.0×1.2mm), built on a Fe-based metal-alloy core for high saturation current and low DCR. 0.33μH~10μH 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): 3012 (3.0×3.0×1.2 mm), 0.33–10 μH — Fe-based metal-alloy core — high saturation current and low DCR.
• Low DCR, high current: DCR 0.023Ω~0.395Ω; saturation current up to 8.90A — high DC-bias performance in a 3012 body.
• Supply: YQM ELECTRONICS holds Sunlord stock with fast samples, datasheets and FAE support for volume programs.

Key Specifications

Cross Reference & Replacement

Cross-reference alternatives:

• TDK — A same-spec part from a globally recognized passive-component maker — compatible footprint, matched process and key parameters, stable worldwide supply; a proven drop-in for this application class.
• Murata — A same-spec part from a leading passive-component maker — matched core features such as magnetic shielding and low DCR; widely used as an alternative in the supply chain.
• Microgate — A same-spec part from a leading Chinese passive-component maker — land-pattern compatible, ample domestic capacity, short lead times and strong cost-performance for localized BOM 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.
