SWPA5040S | Wire Wound SMD Power Inductors (SWPA)
Product Introduction
Sunlord SWPA5040S is a wire-wound SMD power inductor from the SWPA series in 5040 (5.0×5.0×4.0mm). Magnetic-glue coating provides shielding with very low buzz noise, and metallised electrodes add shock resistance; 0.22μH~680μH operates from -40°C~+125°C (including self-heating) in smartphone, TV, STB, notebook, car-navigation, VR/AR and LED-lighting DC-DC rails.
Core Advantages
- Wire Wound SMD Power Inductors (SWPA): 5040 (5.0×5.0×4.0 mm), 0.22–680 μH — magnetic-glue shielding with metallised impact-resistant electrodes and very low buzz noise.
- Low DCR, high current: DCR 0.006Ω~3.9Ω; saturation current up to 20A — high DC-bias performance in a 5040 body.
- Supply: YQM ELECTRONICS holds Sunlord stock with fast samples, datasheets and FAE support for volume programs.

FAQ
Q: How is Isat / Irms defined for SWPA inductors?
A: Isat is the current at which inductance drops about 30 %; Irms is the current causing a 40 °C temperature rise (ΔT = 40 °C).
Q: Is SWPA5040S mechanically robust?
A: Yes — metallised electrodes and the magnetic-glue body improve shock resistance versus conventional molded parts.
