MWSA0412S

Product Introduction

Sunlord MWSA0412S is a molded power inductor from the MWSA-S series in 0412 (4.4×4.2×1.0mm). An iron-alloy powder body forms a closed magnetic circuit with minimal leakage flux; halogen-free and RoHS compliant, covering 0.15μH~4.7μH (0412Sseries) from -55°C~+125°C (including self-heating) for TV, GPU, memory, notebook, tablet, communications and industrial DC-DC converters.

Core Advantages

• Molded Power Inductors (MWSA-S): 0412 (4.4×4.2×1.0 mm), 0.15–4.7 μH — iron-alloy molded closed magnetic circuit — minimal leakage flux, halogen-free.
• Low DCR, high current: DCR 9mΩ~195mΩ; saturation current up to 15A — high DC-bias performance in a 0412 body.
• Compliance: Halogen-free, RoHS compliant.
• Supply: YQM ELECTRONICS holds Sunlord stock with fast samples, datasheets and FAE support for volume programs.

Applications

FAQ

Q: What is the advantage of an iron-alloy molded inductor?

A: The metal-alloy powder is compressed into a solid body — a closed magnetic circuit with strong DC-bias performance, minimal leakage and low buzz noise under load.

Q: Is MWSA0412S halogen-free?

A: Yes — the MWSA-S series is halogen-free and RoHS compliant.
