SRN4018TA Semi-Shielded Power Inductors Bourns SRN4018TA Semi-Shielded Power Inductors provide effective magnetic shielding with lower radiation compared to non-shielded inductors. These inductors offer a reduced cost to comparably-sized conventional ferrite shield inductors. The AEC-Q200 qualified SRN4018TA components are primarily designed for automotive electronics applications. Typical automotive application areas for these inductors are driver assistant devices, information/entertainment systems, lighting, and other applications including DC/DC converters and power supplies. Although primarily designed for automotive applications, Bourns SRN4018TA Inductors are also well suited for consumer, industrial, medical, telecom, and other applications where higher inductor reliability is required.
