Bourns Introduces Automotive Qualified Current Shielded Power Inductors


Bourns has introduced its new automotive grade high-current shielded power inductors, the model SRP7020TA and SRP8540A series, that have been designed to meet high current density and high temperature requirements of various electronic applications. These inductor series are manufactured with a metal alloy powder core featuring low DC resistance, high heating / saturation current, low buzz noise, excellent temperature stability and shielded construction for low magnetic field radiation.

The model SRP7020TA and SRP8540A series are AEC-Q200 compliant with a wide operating temperature range from -55 to 150 °C and are well suited for DC-DC converters and power supplies in consumer, industrial, and telecom electronics applications in which higher inductor reliability may be required.
