CC0805KKX7R7BB105

The "CC0805KKX7R7BB105" 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: Ceramic Capacitor
• Series: CC Series
• Package Size: 0805 (which refers to the dimensions of the capacitor, approximately 0.08 inches by 0.05 inches or 2.0 mm x 1.25 mm)

Electrical Characteristics

• Capacitance Value: 1 µF (microfarad)
• Dielectric Material: X7R, which is a type of ceramic dielectric that offers a good balance between capacitance stability and temperature performance. X7R capacitors can handle a wide range of temperatures and have a moderate capacitance change with voltage and temperature.
• Voltage Rating: 25V (this 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.

Physical Characteristics

• Construction: The capacitor is typically constructed with a ceramic dielectric material sandwiched between two conductive plates, which are usually made of a metal layer. The 0805 package size indicates a surface-mount design, making it suitable for automated assembly processes.
• Terminations: The capacitor features solderable terminations that allow for easy mounting on printed circuit boards (PCBs).

Performance Attributes

• Temperature Range: The X7R dielectric allows the capacitor to operate effectively over a temperature range of -55°C to +125°C, making it suitable for various applications, including automotive and industrial environments.
• Voltage Coefficient: The capacitance may decrease under DC bias voltage, which is a characteristic of ceramic capacitors, particularly those with higher capacitance values.
