Bourns Introduces Shielded Power Inductor Series with Metal Alloy Powder Core Capable of Handling High Currents with Very Low DCR
28 August 2025 Bourns, a global manufacturer and supplier of electronic components for power, protection, and sensing solutions, has announced its SRP3220A Series Shielded Power Inductors.
The company says designed with its uniquely-formulated metal alloy powder core, the series can handle high currents up to 11 A without saturating, and supports reliable operation in high-temperature environments. These automotive grade, AEC-Q200 compliant power inductors feature a high heating current rating and shielded construction that minimises magnetic field radiation. The capabilities delivered with the SRP3220A Series also help enhance performance, thermal stability and meet demanding automotive temperature requirements making Bourns’ latest power inductors a cost-effective and efficient power management solution for a growing range of automotive systems.
The SRP3220A Series is offered in a space-saving, low-profile form factor and features a wide operating temperature range of -55 °C to 150 °C. In addition to the advantages realised by the series’ metal alloy powder core, its flat-wire construction also contributes to very low DC resistance (DCR) compared to other similarly-sized shielded power inductors. Moreover, the low profile footprint offered with these power inductors occupies less printed circuit board (PCB) space, giving engineers the flexibility to design-in additional capabilities or match reduced space requirements.
Bourns says its SRP3220A Series is available now through its authorised distribution partners, and is RoHS compliant.
