This is a 10pF, 50V, 0402 RoHS compliant Multilayer Ceramic Capacitor (MLCC) produced by Prosperity. This Part number is FN15N100J500PNG, and it is a surface mount device (SMD/SMT). This capacitor has a temperature coefficient of ±10% over the temperature range of -55C to +150C. The capacitance value, voltage rating, and package size can vary within this particular series, providing design engineers a broader choice of options. The dielectric used for this capacitor is Niobium Oxide (NbO), lending a lower dissipation factor, higher insulation resistance, and greater thermal shock resistance compared to other ceramic dielectrics.
