Bourns Expands Line with Three New Semi-Shielded Power Inductor Series Featuring High Operating Temperature

New power inductors are AEC-Q200 compliant and meet high-reliability requirements in EMI filtering, DC-DC converter and power supply applications

RIVERSIDE, Calif., February 24, 2022 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the expansion of its power inductor line with three new semi-shielded power inductor model series, Model SRN3030HA, SRN4030HA, and SRN5030HA. The new AEC-200 compliant power inductors from Bourns are designed with high current capacity, compact size, low loss, high operating frequency, and high operating temperature. The high temperature-graded materials employed in all three series achieve a 150 °C operating temperature rating and provide a wide operating temperature range of –55 to +150 °C. These features and capabilities make Bourns' latest power inductors ideal, high reliability power conversion solutions for EMI filtering, DC-DC converters and power supplies in consumer, industrial, and telecom electronics.

A magnetic-silica based coating applied to the perimeter of the inductor winding enhances the inductors' shielding and reduces magnetic field radiation compared to non-shielded options. Additionally, semi-shielded construction contributes to a lower component cost compared to similarly-sized conventional ferrite-shielded inductors. Each series offers different heating current ratings with saturation currents from 5 A to 10 A. Both Model SRN3040HA and SRN4030HA series have inductance ranges of 1-100 μH, and the SRN5030HA has a range of 0.47-100 μH. High Q values of 13 to 33 are possible in these compact power inductors, which provide high impedance at resonance frequency in combination with low loss operation.

Bourns Model SRN3030HA, SRN4030HA, and SRN5030HA power inductors are available now and are RoHS compliant* and halogen free**. For more detailed product information, please see: www.bourns.com/products/magnetic-products/power-inductors-smd-semi-shielded
