C0805C104K3RAC7800

The part number "C0805C104K3RAC7800" refers to a specific type of ceramic capacitor manufactured by KEMET, a well-known company in the field of electronic components. Here’s a detailed description of this component:

General Description:

• Type: Ceramic Capacitor
• Capacitance: 100,000 pF (or 0.1 µF)
• Dielectric Material: C0G (also known as NP0), which is a type of temperature-stable ceramic dielectric. This type of dielectric is known for its low loss and high stability over a wide temperature range.
• Voltage Rating: 50V, indicating the maximum voltage the capacitor can handle without breaking down.
• Package Size: 0805, which refers to the dimensions of the capacitor. The "08" indicates a width of 0.08 inches (2.0 mm), and the "05" indicates a length of 0.05 inches (1.25 mm). This is a common surface-mount package size.
• Tolerance: ±10%, meaning the actual capacitance can vary by 10% above or below the nominal value of 100 nF.
• Temperature Coefficient: The C0G dielectric has a temperature coefficient of 0, which means it exhibits minimal capacitance change with temperature variations, making it suitable for precision applications.

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 such as nickel or silver. The entire assembly is encapsulated in a protective layer to ensure reliability and durability.
• Lead Type: Surface Mount Device (SMD), which means it is designed to be mounted directly onto the surface of a printed circuit board (PCB) rather than through holes.

Applications:

• This type of capacitor is commonly used in high-frequency applications, decoupling, filtering, and timing circuits due to its stability and low loss characteristics. It is suitable for use in consumer electronics, telecommunications, automotive electronics, and industrial applications.

Compliance and Standards:

• KEMET capacitors typically comply with various industry standards, including RoHS (Restriction of Hazardous Substances), ensuring that they are environmentally friendly and free from certain hazardous materials.

Summary:

The KEMET C0805C104K3RAC7800 is a high-quality, surface-mount ceramic capacitor with a capacitance of 0.1 µF, a voltage rating of 50V, and a C0G dielectric that provides excellent stability and low loss. Its compact 0805 package makes it ideal for modern electronic designs where space is at a premium.
