The FM21X102K201PXG is a multilayer ceramic capacitor (MLCC) with SMD/SMT construction, manufactured by Prosperity, which is rated at 1nF at 200V. The component also features 0805 RoHS packaging, making it ideal for surface mount applications. The capacitors have a wide frequency range, providing excellent performance and reliability for high frequency signal mixing. Their size also makes them a great choice for applications where large components are not feasible. These capacitors offer superb insulation characteristics, due to their high dielectric strength, and resistance to mechanical stresses such as vibration and shock. In addition, their low ESR and ESL characteristics makes them great for power supply decoupling and signal noise elimination.
