High-Current Shielded Power Inductors – SRP3212 Series

Bourns’ SRP3212 series inductors are manufactured with a molding process of metal alloy powder cores featuring high saturation currents, high heating currents, and shielded construction for low magnetic field radiation. The flat wire construction reduces DCR significantly compared to other similar-sized devices that use conventional wire, making these inductors highly efficient. Bourns has expanded this series with the SRP3212-1R0MR21. Offering a much higher Q factor and lower DCR rating than the standard 1 µH inductor in the SRP312 series, this part is specifically developed for use with Texas Instruments' BQ25638/BQ25638D battery chargers and is well-suited for use in DC/DC converters and consumer electronics.

SRP3212 inductor series has an operating temperature range of -40°C to +125°C, a small footprint, and a low profile. The features of these inductors make them a good choice for applications in wearable devices, HDDs, SSDs, smartphones, and LCDs.
