series introduction

# Introduction to the C0805C473G3GACTU Product Series

## 1. Overview
The C0805C473G3GACTU 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 essential functions such as energy storage, filtering, coupling, and decoupling. The series is designed to meet the high - performance requirements of modern electronic devices, offering reliability and stability in various applications.

## 2. Product Naming Convention
Let's break down the product code "C0805C473G3GACTU" to understand its key features:
- **C**: Usually indicates that it is a ceramic capacitor.
- **0805**: This represents the physical size of the capacitor, also known as the package size. In the imperial system, 0805 corresponds to a length of 0.08 inches (2.032 mm) and a width of 0.05 inches (1.27 mm). This standard size makes it compatible with many printed circuit board (PCB) designs and surface - mount technology (SMT) assembly processes.
- **C**: It may refer to a specific dielectric type. In ceramic capacitors, different dielectric materials have different electrical properties, such as temperature coefficient and capacitance stability.
- **473**: This is the capacitance value code. Using the standard capacitor coding system, the first two digits (47) are the significant figures, and the third digit (3) is the multiplier. So, the capacitance value is \(47\times10^{3}\) pF, which is equal to 47 nF or 0.047 μF.
- **G**: This could represent the tolerance of the capacitance. For example, a "G" might indicate a tolerance of ±2%. This means that the actual capacitance of the capacitor can vary within ±2% of the nominal value (47 nF in this case).
- **3G**: This part of the code may be related to additional electrical characteristics, such as voltage rating or temperature coefficient.
- **AC**: It might signify certain application - specific features or compliance with particular standards.
- **TU**: This could be a manufacturer - specific code for product version or other internal details.

## 3. Electrical Characteristics

### Capacitance
As mentioned earlier, the nominal capacitance of the C0805C473G3GACTU series is 47 nF. The capacitance value is carefully controlled during the manufacturing process to ensure that it falls within the specified tolerance range. This accurate capacitance value is essential for the proper functioning of circuits, especially in applications where precise timing or filtering is required.

### Tolerance
With a tolerance of ±2% (assuming "G" represents this tolerance), the actual capacitance of the capacitor can range from \(47\times(1 - 0.02)\) nF = 46.06 nF to \(47\times(1 + 0.02)\) nF = 47.94 nF. This tight tolerance allows for more predictable circuit performance compared to capacitors with wider tolerances.

### Voltage Rating
The voltage rating of the C0805C473G3GACTU series is an important parameter. It indicates the maximum voltage that the capacitor can safely withstand without experiencing breakdown or significant degradation in performance. The specific voltage rating can be determined from the manufacturer's datasheet. For example, if the voltage rating is 50 V, the capacitor should not be exposed to voltages higher than 50 V in normal operation.

### Temperature Coefficient
The temperature coefficient of the capacitor describes how the
