Additional Details:
The 1812FS-474JLC inductor features a ferrite core, which contributes to its high inductance and current handling capabilities. The inductance value is 470 µH, as indicated by the '474' in the part number (47 x 10^4 nH = 470 µH). The shielded construction minimizes electromagnetic interference (EMI), making it suitable for sensitive applications. The component is designed for reflow soldering and is RoHS compliant. It's important to consult the Coilcraft datasheet for detailed specifications, including the saturation current, DC resistance (DCR), and self-resonant frequency (SRF). Exceeding the saturation current can significantly reduce the inductance value. Proper PCB layout design is essential to minimize parasitic inductance and capacitance, which can affect the inductor's performance. The inductor's robust construction ensures reliable performance in demanding environments. The shielded design is particularly important in applications where minimizing EMI is critical.
