series introduction
# Introduction to the C0805C682K1RAL Product Series
## 1. Overview
The C0805C682K1RAL product series belongs to the category of electronic components, specifically ceramic capacitors. These capacitors play a crucial role in a wide range of electronic circuits, providing functions such as energy storage, filtering, coupling, and decoupling. The "C0805" in the product code indicates the capacitor's package size, which is a standard 0805 surface - mount package. This package size is widely used in modern electronics due to its relatively small footprint and good compatibility with automated assembly processes.
## 2. Electrical Specifications
### Capacitance
The "682" in the product code represents the capacitance value. Using the standard capacitor coding system, the first two digits (68) are the significant figures, and the third digit (2) is the multiplier. So, the capacitance value is \(68\times10^{2}pF = 6800pF=6.8nF\). This capacitance value is suitable for a variety of applications where a moderate amount of charge storage is required, such as in high - frequency filtering circuits.
### Tolerance
The "K" in the product code indicates the capacitance tolerance. A "K" tolerance means that the actual capacitance value of the capacitor can deviate from the nominal value (\(6.8nF\)) by ±10%. This level of tolerance is acceptable for many general - purpose applications, but in more precise circuits, such as those in high - end communication or measurement equipment, a capacitor with a tighter tolerance may be required.
### Voltage Rating
The "1R" in the product code represents the voltage rating. In this case, the voltage rating is 100V. This means that the capacitor can safely operate in a circuit where the maximum voltage across it does not exceed 100V. It is important to select a capacitor with an appropriate voltage rating to ensure the reliability and safety of the circuit. If the voltage across the capacitor exceeds its rated voltage, it may lead to dielectric breakdown, which can damage the capacitor and potentially other components in the circuit.
### Temperature Coefficient
Although not explicitly mentioned in the product code, ceramic capacitors in this series typically have a certain temperature coefficient. The temperature coefficient describes how the capacitance value changes with temperature. Different types of ceramic dielectrics have different temperature coefficients. For example, Class II ceramic capacitors, which are commonly used in general - purpose applications, may have a relatively large temperature coefficient compared to Class I ceramic capacitors. This can affect the performance of the circuit in environments with significant temperature variations.
## 3. Physical Characteristics
### Package Size
As mentioned earlier, the 0805 package size has dimensions of approximately 2.0mm x 1.25mm. This small size makes it suitable for use in compact electronic devices, such as mobile phones, tablets, and wearable devices. The surface - mount design allows for easy and efficient assembly on printed circuit boards (PCBs) using automated pick - and - place machines.
### Termination
The capacitor has metal terminations that provide electrical connections to the PCB. These terminations are designed to ensure good solderability and mechanical stability. The quality of the terminations is important for reliable electrical contact and long - term performance of the capacitor in the circuit.
## 4. Applications
### Power Supply Filtering
In power supply circuits, the C0805C682K1RAL capacitors can be used to filter out high - frequency noise and ripple. They are connected in parallel with the power supply to provide a low - impedance path for high - frequency currents, thereby smoothing the DC voltage output. This helps to improve the stability and reliability of the power supply, which
