Bourns has announced the launch of two new automotive class high-current shielding power inductors to provide enhanced mechanical strength for harsh vibration applications. Bourns models SRP1038WA and SRP1265WA shielded power inductor series are designed with wider side terminal lead frames capable of withstanding 15 G typical or 30 G peak vibration, thus exceeding the 5 G 3x and 6 x * required by the AAC-Q200 standard, respectively.

     Vibration tests were performed according to Method 204 of MIL-STD-202. Both series also feature compact packaging, high saturation current, low DC resistance, low buzzing noise, and excellent temperature stability C over a wide temperature range of -- 55 to +165°. These characteristics make these AEC-Q200 compliant automotive grade power inductors ideal for power management and EMI filtering in a variety of consumer, automotive, industrial and telecom electronics applications.

     The two new systems, listed as Bourns industry leading shielded power inductors, add advanced features over existing Bourns models to increase the width of the side terminal frame by more than 50% without increasing the package size or required printed circuit board area. Bourns uses a uniquely formulated metal alloy powder magnetic core and adhesive and uses a molded structural manufacturing process where the magnetic shield design allows for low radiation while the metal alloy powder magnetic core provides high saturation current.

     High temperature grade materials are used to achieve a wide operating temperature range suitable for a variety of harsh environment applications. These new models have a maximum operating temperature of +165 °C, 10% higher than the standard Bourns model SRP-A power inductor, and offer more room to maintain rated operating current even under challenging environmental conditions.
