SRU Automotive Shielded Power Inductors Bourns Automotive SRU Automotive Shielded Power Inductors are designed to discharge minimum magnetic flux radiation when the inductor is operating at high-frequency ripple currents. SRU inductors are manufactured for automotive applications and feature a 1µH to 330μH inductance range. Typical automotive applications include driver assistant devices, information/entertainment systems, and lighting. Bourns SRU inductors are AEC-Q200 qualified, and the electrical characteristics and dimensions are functionally equivalent to the existing standard series.
