MWSA0518S | Molded Power Inductors (MWSA-S)
Product Introduction
Sunlord MWSA0518S is a molded power inductor from the MWSA-S series in 0518 (5.4×5.1×1.8mm). An iron-alloy powder body forms a closed magnetic circuit with minimal leakage flux; halogen-free and RoHS compliant, covering 0.22μH~10μH 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): 0518 (5.4×5.1×1.8 mm), 0.22–10 μH — iron-alloy molded closed magnetic circuit — minimal leakage flux, halogen-free.
- Low DCR, high current: DCR 4.8mΩ~155mΩ (Max); saturation current up to 21.5A — high DC-bias performance in a 0518 body.
- Compliance: RoHS + halogen-free.
- Supply: YQM ELECTRONICS holds Sunlord stock with fast samples, datasheets and FAE support for volume programs.

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 MWSA0518S halogen-free?
A: Yes — the MWSA-S series is halogen-free and RoHS compliant.
