Bourns Releases New Automotive High Temperature Semi-shielded Power Inductors

Bourns Magnetics product line is introducing the new automotive AEC-Q200 compliant model SRN3030HA, SRN4030HA and SRN5030HA series high temperature semi-shielded power inductors.

Constructed with a magnetic-silica coating to the perimeter of the inductor winding to provide effective shielding, these inductors release lower magnetic field radiation compared to non-shielded inductors. These new semi-shielded inductors are lower priced than typical comparably-sized conventional ferrite shielded inductors.

The Model SRN3030HA, SRN4030HA and SRN5030HA Series feature high temperature and have been designed to meet a broad operating temperature range from -55 to +150 °C. These inductors are well suited for DC-DC converters and power supplies in consumer, industrial and telecom applications where enhanced inductor reliability may be required.
