Bourns Announces Automotive Grade Semi-Shielded Power Inductor Series with High Temperature Ratings

Model SRN6045HA power inductors feature a wide operating temperature range up to 125 °C and are AEC-Q200 compliant for high reliability in certain harsh environments

RIVERSIDE, Calif., August 4, 2021 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced its automotive grade Model SRN6045HA power inductor series. These new inductors feature semi-shielded construction to combine the features of non-shielded and shielded inductors, and offer lower magnetic field radiation than non-shielded inductors. The new products are a more cost-efficient alternative to fully shielded ferrite-based inductors, yet allow high temperature operation compared to standard semi shielded inductors. In addition, the new inductor series is AEC-Q200 compliant with an operating temperature range of -55 to +125 °C making the Model SRN6045HA series ideal for power management and electromagnetic interference (EMI) filtering solutions in automotive, consumer, industrial and telecom electronics.

The newly developed magnetic silicon-based coating used in the new inductors enables high working temperatures and extends the operating temperature range by 20 percent on the high end compared to standard Bourns® semi-shielded power inductors. The high-temperature magnetic silicon-based coating is applied to the perimeter of the inductor winding to provide effective magnetic shielding. Along with its high operating temperature, compact size and low losses, the Model SRN6045HA series also features high current capacity with saturation current Isat ranging from 1.2 – 18 A and heating current Irms of 0.72 – 7.0 A.

The Bourns® automotive grade SRN6045HA series is available now with inductance values of 0.55 – 100 µH and is RoHS compliant* and halogen free**. For more detailed product information, please see:

*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.
