Additional Details:

The 0402CS-22NXJEW features an inductance value of 22 nH. Its Self-Resonant Frequency (SRF) indicates the frequency at which the inductor's performance begins to degrade. The DC resistance (DCR) is typically low, which contributes to its high Q. It's designed to be compatible with reflow soldering processes. Always adhere to the manufacturer's recommended reflow profile to ensure proper solder joint formation and prevent component damage. This inductor is commonly employed in impedance matching to optimize signal transfer, in RF filtering to attenuate unwanted signals, and in oscillator circuits to set the oscillation frequency. Always refer to the Coilcraft datasheet for the most accurate and current specifications, including SRF, DCR, and recommended soldering profiles.
