SPH4012H

Product Introduction

Sunlord SPH4012H is a wire-wound SMD power inductor from the SPH series in 4012 (4.0×4.0×1.2mm), using a magnetic-glue coated construction. Magnetically shielded with low DCR and high saturation current, it covers 0.33μH~100μH (4012Hseries) from -40°C~+125°C (including self-heating) for mobile, mobile-PC, wearable and industrial DC-DC converter circuits.

Core Advantages

• Wire Wound SMD Power Inductors (SPH): 4012 (4.0×4.0×1.2 mm), 0.33–100 μH — magnetic-glue coated shielded structure — low DCR, high Isat and low buzz noise.
• Low DCR, high current: DCR 0.026Ω~2.04Ω; saturation current up to 6.30A — high DC-bias performance in a 4012 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:

• Murata — 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.
• TDK — 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.
• Fenghua Advanced — 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 is a magnetic-glue coated construction?

A: The winding is encapsulated in magnetic adhesive instead of a ferrite clamp — a smaller, lower-profile, magnetically shielded body with low buzz noise under load.

Q: Is SPH4012H suitable for high-temperature environments?

A: Yes — the rating covers -40°C~+125°C including self-temperature rise, with inductance tested at 1 MHz / 0.1 MHz, 1 V.
