Overview

The Coilcraft 1812CS-392XGLC is a high-performance unshielded wirewound RF inductor designed for demanding signal path applications. Its 3.9 µH inductance with a tight 2% tolerance and a respectable Q factor of 69 at 7.9 MHz make it ideal for precise filtering and impedance matching. A critical design consideration for this AEC-Q200 qualified component is its self-resonant frequency (SRF) of 130 MHz; designers must ensure the operating frequency remains well below this limit to avoid significant performance degradation due to parasitic capacitance, especially in broadband circuits.
