Power inductors withstand automotive temperature and current

September 16, 2025 By Redding Traiger Leave a Comment

Bourns, Inc. announced its SDE0403AT Series SMD Power Inductors. The new series handles high currents without saturation and temperatures up to 150 °C, helping to ensure stable and reliable operation in high-temperature environments. These automotive-grade, AEC-Q200-compliant SMD power inductors deliver high current density in a low-profile form factor, making them ideal for automotive designs requiring exceptional power efficiency and design flexibility. The features designed into Bourns’ latest power inductors are optimized for use in a broad variety of advanced automotive applications, including noise filters and DC power lines.

In addition, the SDE0403AT Series features a uniquely designed drum ferrite structure in a compact, low form factor, giving designers greater layout flexibility and ease of system integration. The series supports a wide operating temperature range from -55 °C to +150 °C and delivers a high saturation current up to 4.8 A, helping maintain thermal stability in today’s sophisticated automotive systems.

The Bourns SDE0403AT Series is available now through Bourns’ authorized distribution partners, and is RoHS* compliant and halogen** free.
