Additional Details:

The 1812CS-472XKBC has an inductance value of 4.7 uH. Its Self-Resonant Frequency (SRF) is an important characteristic that determines the upper frequency limit for its effective use. The DC resistance (DCR) is typically low, contributing to its high Q. The part is designed for reflow soldering. It is crucial to follow the manufacturer's recommended reflow profile to ensure proper solder joint formation and avoid component damage. This inductor is commonly used in impedance matching circuits, RF filters, and tank circuits. Its compact size makes it ideal for applications where board space is limited.
