CC0402KRX7R9BB561

The "CC0402KRX7R9BB561" is a specific type of ceramic capacitor manufactured by Yageo, a well-known company in the electronic components industry. Here’s a detailed description of this component:

General Overview

• Type: Multilayer Ceramic Capacitor (MLCC)
• Package Size: 0402 (which refers to a size of 0.04 inches by 0.02 inches, or approximately 1.0 mm x 0.5 mm)
• Dielectric Material: X7R, which is a type of ceramic dielectric that offers a moderate capacitance change with temperature and voltage.

Electrical Characteristics

• Capacitance Value: 560 pF (picoFarads)
• Voltage Rating: Typically rated at 25V, which indicates the maximum voltage the capacitor can handle without breaking down.
• Tolerance: ±10%, meaning the actual capacitance can vary by 10% above or below the nominal value of 560 pF.

Physical Characteristics

• Construction: The capacitor is constructed using multiple layers of ceramic material, which allows for a compact design while maintaining high capacitance values.
• Terminations: The capacitor features nickel barrier terminations, which are suitable for soldering onto printed circuit boards (PCBs).
• Color and Markings: The capacitor is usually unmarked or has minimal markings due to its small size, but it typically has a beige or light-colored body.

Performance Characteristics

• Temperature Coefficient: The X7R dielectric has a temperature coefficient of ±15% over a temperature range of -55°C to +125°C, making it suitable for a variety of applications where temperature stability is important.
• Voltage Coefficient: The capacitance may decrease under high DC bias voltage, which is a characteristic of ceramic capacitors, particularly those with X7R dielectric.

Applications

• Usage: This capacitor is commonly used in decoupling, filtering, and coupling applications in various electronic circuits, including consumer electronics, automotive, and industrial devices.
• Ideal for: High-frequency applications due to its low equivalent series resistance (ESR) and equivalent series inductance (ESL).

Compliance and Standards

• RoHS Compliant: The capacitor is compliant with the Restriction of Hazardous Substances (RoHS) directive, indicating it is free from certain hazardous materials.
• Quality Standards: Yageo adheres to various quality standards, ensuring reliability and performance in their components.
