The Yageo AC0402KRX7R9BB103 is a 10nF multilayer Ceramic Capacitor rated at 50V with a 10% tolerance, equivalent to the 0.01uF value quoted in its product title. It uses an X7R dielectric as identified in both the part number and the product title, and is specified over a -55 to 125 degrees C operating range. The AC0402KRX7R9BB103 is built in an 0402 case measuring 990.6um by 508um with a 550um height for surface-mount assembly. Yageo supplies the part lead free and RoHS compliant.

X7R is the workhorse class-2 dielectric, holding capacitance within 15% across its full -55 to 125 degrees C range, which is why it is specified where an X5R part would drift too far but a class-1 dielectric would be too large or too costly. At 10nF the AC0402KRX7R9BB103 is used for high-frequency supply decoupling next to IC power pins, RC filtering and timing networks, EMI suppression on signal and interface lines, snubbers and AC coupling. The 0402 case and 50V rating make it a general-purpose part across consumer, computing, networking, industrial and automotive-adjacent boards rather than a specialist one. Buyers are contract manufacturers and OEMs consuming Ceramic Capacitors in full reel volumes, where this value and case size are among the highest-running lines in the catalog.
