The FN15N681J500PNG is a Prosperity-manufactured Multilayer Ceramic Capacitor (MLCC) with a surface mount/surface mount technology package. It has a capacitance of 680pF, a working voltage of 50V, and a maximum tolerance of ±10%. It is rated to a temperature range of -55°C to 125°C and is RoHS compliant. The MLCC utilizes two sets of electrodes within a ceramic dielectric material, equidistant from the center of the component and separated by a dielectric layer to create a capacitor. It is typically used for filtering, smoothing, and decoupling applications in audio circuits, automotive electronics, power supplies, and digital communication circuits.
