Model SRP1038WA and SRP1265WA power inductors feature a wide side terminal frame to withstand 15 G typical or 30 G peak vibrations

RIVERSIDE, Calif., February 21, 2022 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced two new automotive grade high current shielded power inductor series that offer enhanced mechanical strength for harsh vibration application environments.

Bourns® Model SRP1038WA and SRP1265WA shielded power inductor series are designed with a wider side terminal leadframe capable of withstanding 15 G typical or 30 G peak vibrations, therefore exceeding the 5 G demanded by the AEC-Q200 standard by a factor of three and six times, respectively*. Vibration testing was conducted according to MIL-STD-202 Method 204. The two series also feature a compact package, high saturation current, low DC resistance, low buzz noise and excellent temperature stability over a wide temperature range of –55 to +165 °C. Such features make these automotive grade, AEC-Q200 compliant power inductors ideal for power management and EMI filtering in a wide range of consumer, vehicle, industrial and telecom electronics applications.

The two new series add advanced capabilities to Bourns’ industry-leading shielded power inductor portfolio by increasing the width of the side terminal frame by more than 50 percent compared to existing Bourns® models without increasing the package size or required printed circuit board area. Bourns employs a uniquely-formulated metal alloy powder core and bonding agent and uses a molded construction manufacturing process where the magnetic shielded design allows for low radiation while the metal alloy powder core provides high saturation current. The high temperature-grade materials used enable a wide operating temperature range suitable for many types of harsh environment applications. The maximum operating temperature of +165 °C for these new models is 10 percent higher than standard Bourns® Model SRP-A power inductors and the new models provide more headroom to maintain the rated operating current even under challenging environmental conditions.

Bourns® Model SRP1038WA and SRP1265WA power inductors are available now and are RoHS compliant** and halogen free***. For more detailed product information, please see: www.bourns.com/resources/rohs/magnetics/power-inductors-smd-shielded.

*RoHS Directive 2015/863, Mar 31, 2015 and Annex.

**Bourns considers a product to be "halogen free" if (a) the Bromine (Br) content is 900 ppm or less; (b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less.
