The Bourns SRF1280-3R3Y is a dual coil inductor array designed for high current and low DC resistance applications. Each coil provides 3.3 µH inductance with ±30% tolerance, measured at 100 KHz.
The maximum DC resistance is 0.011Ω, enabling efficient power handling. The component is rated for 5.23 A (Irms) in parallel configuration and 10.4 A in series, with a saturation current of 21.5 A for both modes. Operating temperature ranges from -40°C to 125°C.
The package is a surface mount nonstandard format measuring 12.50mm x 12.50mm x 8.00mm. The dual coil architecture allows flexible wiring configurations for different inductance and current levels.
