Bourns Releases New Semi-Shielded Power Inductor Series with a High Q Value and Miniature Size

Model SRN2012T power inductors feature a semi-shielded wirewound construction and high performance for RF signal processing and DC power line applications

RIVERSIDE, Calif., November 2, 2021 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today released its Model SRN2012T semi-shielded power inductor series. The new inductors employ wirewound construction on a ferrite core to offer high inductance and Q values. They also offer a superior self-resonant frequency plus low DC resistance in a compact size with an operating temperature range of -40 to +125 °C. Such features make this series ideal for RF signal processing, resonant circuits, decoupling and noise filters, and DC power line applications for audio headsets, true wireless stereo headsets, cable modems, set-top boxes, hard disk drives, tablets, and various mobile electronic devices.

Applying a magnetic-epoxy coating to the perimeter of the inductor winding provides enhanced shielding and lower magnetic field radiation compared to non-shielded options. Since wirewound construction provides better performance than multilayer or film around the core construction, lower DC resistance and high Q values of 13 to 15 are possible in these miniature-sized power inductors. High Q values provide a high impedance at resonance in inductive-capacitive circuits and low loss at high frequency operation. Bourns® Model SRN2012T power inductors also feature a high self-resonant frequency, which enables low distributed capacitance and consistent inductive characteristics over a wide frequency span. With saturation current up to 1100 mA and rated current up to 1300 mA, these new power inductors from Bourns maintain high inductance at a greater peak current and meet the requirements of common DC power line applications.

Bourns® Model SRN2012T 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

*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.
