The SRN4012TA-R47M is a semi-shielded power inductor from Bourns designed for high-current applications requiring low inductance values. It features a nominal inductance of 0.47 µH at 100 kHz with ±20% tolerance, a DC resistance of 0.025 O, and a self-resonant frequency of 140 MHz. The inductor is rated for 3.2 A RMS current with a saturation current of 4 A, and operates reliably across a temperature range of -40°C to +125°C with a maximum temperature rise of 40°C at rated current. The device is AEC-Q200 qualified, RoHS compliant, and halogen-free, making it suitable for automotive and industrial power conversion circuits, switching regulators, and EMI filtering applications where compact size and high current handling are essential.
