New automotive grade, AEC-Q200 compliant SRN5040TA-P Series meets stringent temperature and reliability requirements for advanced automotive systems
RIVERSIDE, Calif., September 24, 2025 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today announced its SRN5040TA-P Series of Semi-Shielded Power Inductors. The new series features polarity control that optimizes Electromagnetic Interference (EMI) protection for a wide range of automotive systems. These automotive grade, AEC-Q200 compliant semi-shielded power inductors provide excellent power management performance and thermal stability, meeting the demanding temperature and reliability requirements of advanced systems, including DC-DC converters, power supplies, driver assistance, infotainment and lighting systems.
The new SRN5040TA-P semi-shielded power inductors feature a specialized construction that minimizes magnetic field radiation while delivering high heating current and saturation current capabilities. In addition, the series supports a wide operating temperature range of -55 °C to +125 °C, making it ideal for space-constrained automotive applications. The semi-shielded design utilizes a magnetic-epoxy coating around the winding perimeter, providing effective EMI suppression and lower magnetic field radiation compared to non-shielded inductors.
The Bourns® SRN5040TA-P Series is available now through Bourns’ authorized distribution partners. It is RoHS* compliant and halogen** free. For more detailed product information, please see: bourns.com/products/magnetic-products/power-inductors-aec-q200-compliant.
*RoHS Directive 2015/863, Mar 31, 2015 and Annex.
