Additional Details

Analyzing the part number, 'SA102' most likely corresponds to the case size and series of the capacitor. 'C' usually denotes the temperature coefficient. '221' indicates the capacitance value (22 x 10^1 pF = 220 pF). 'J' represents the capacitance tolerance, typically +/- 5%. 'AR' may relate to the termination material or packaging specifics. Consulting the manufacturer's datasheet is crucial to obtain precise electrical characteristics such as voltage rating, temperature specifications, and recommended solder reflow profiles. These capacitors are built with alternating layers of ceramic dielectric and metal electrodes, terminated appropriately for surface mount soldering. Proper soldering practices are important for preserving component integrity during the assembly process.
