Automotive-grade, AEC-Q200-compliant "SDE0403AT Series" improves power efficiency and supports flexible circuit design with high current density and low profile

Riverside, Calif. – September 16, 2025 – Bourns, a leading manufacturer of electronic components for power, protection, and sensing solutions, introduces the SDE0403AT series of SMD power inductors. This new series supports high currents without saturating, providing stable and reliable operation in high-temperature environments up to 150°C. Compliant with AEC-Q200, this automotive-grade product offers high current density in a low profile, making it ideal for automotive applications requiring superior power efficiency and design flexibility. Its features, including noise filtering and DC power lines, are optimized for a wide range of advanced automotive applications.

Furthermore, the SDE0403AT series uses a proprietary drum-type ferrite structure, resulting in a compact, thin form factor that improves layout flexibility and ease of system integration. With a wide operating temperature range of -55°C to +150°C and a high saturation current of up to 4.8A, the SDE0403AT series contributes to ensuring thermal stability in increasingly complex automotive systems.

The SDE0403AT series is currently available and is RoHS compliant (*1) and halogen-free (*2).
