MWSA0503S-100MT High-Current Shielded Molded Power Inductor (10µH, 3.2A+, 125mΩ max, SMD)

Ensure stable power delivery and high conversion efficiency in your DC-DC buck/boost circuits with the MWSA0503S-100MT molded power inductor. Delivering 10 µH inductance in a compact $5.4 \times 5.2 \text{ mm}$ footprint with a low profile of $3.0 \text{ mm}$, this metal-alloy shielded inductor is engineered for demanding power supply applications requiring low DC resistance ($\le 125\text{ m}\Omega$) and high saturation currents ($3.2\text{A}+$ handling capacity).

Built with a fully enclosed iron-powder / metal-alloy molded core, the MWSA0503 series offers superior magnetic shielding against electromagnetic interference (EMI) and eliminates audible magnetostrictive noise (hum/buzz). It is an ideal choice for compact DC-DC converters, embedded power modules, automotive infotainment systems, LED drivers, and industrial control electronics.

Key Features:

• 10 µH Inductance & 3.2A+ Rating: Excellent current handling capability in a compact 5x5mm body.

• Low DC Resistance ($\le 125\text{ m}\Omega$): Reduces copper losses to maximize overall circuit efficiency and minimize heat generation.

• Metal-Alloy Molded Shielding: Protects sensitive adjacent components from electromagnetic radiation (EMI) and prevents acoustic noise.

• Low Profile (3.0mm): Fits easily into space-restricted, slim electronic enclosures.
