The CS0603KRX7R9BB103 is a 10 nF, 50 V, 10% ceramic multilayer capacitor (MLCC) manufactured by Yageo. It has a small surface mount design and is highly durable, able to handle high shock and vibration. It is ideal for applications requiring high capacitance in tight spaces. This MLCC has an operating temperature range of -55 to +125 degrees C, and is ideal for use in high-frequency circuits and power circuits. It has a low-impedance design, making it well-suited for use in high-temperature environments and for high-power density designs. It also has good heat resistance, making it ideal for use in automotive, telecommunication, and industrial applications.
