# Introduction to the C0805C182G3GACTU Product Series
## 1. Overview
The C0805C182G3GACTU product series belongs to the realm of electronic components, specifically capacitors. Capacitors are fundamental building - blocks in electronic circuits, and this series offers unique features and performance characteristics that make it suitable for a wide range of applications.
## 2. Physical Specifications
### 2.1 Package Size
The "0805" in the part number indicates the package size of the capacitor. In the imperial measurement system, an 0805 package has dimensions of approximately 0.08 inches (2.032 mm) in length and 0.05 inches (1.27 mm) in width. This relatively compact size makes it suitable for use in printed circuit boards (PCBs) where space is at a premium, such as in mobile devices, wearables, and small - form - factor consumer electronics.
### 2.2 Construction
These capacitors are typically constructed using ceramic materials. The ceramic dielectric provides several advantages, including high dielectric constant, which allows for a relatively large capacitance value to be achieved in a small physical size. The construction also ensures good mechanical stability and resistance to environmental factors such as temperature and humidity.
## 3. Electrical Specifications
### 3.1 Capacitance
The "182" in the part number represents the capacitance value. Using the standard capacitor coding system, the first two digits (18) are the significant figures, and the third digit (2) is the multiplier. So, the capacitance value is \(18\times10^{2}\) pF, which is equal to 1800 pF or 1.8 nF. This capacitance value is well - suited for applications such as coupling, decoupling, and filtering in electronic circuits.
### 3.2 Voltage Rating
The voltage rating of the C0805C182G3GACTU series is an important parameter. It indicates the maximum voltage that the capacitor can withstand without experiencing breakdown or significant degradation in performance. The specific voltage rating for this series is determined by the "G3" part of the part number. This voltage rating ensures that the capacitor can operate safely in circuits with appropriate voltage levels, protecting the component and the overall circuit from damage.
### 3.3 Tolerance
The tolerance of the capacitor refers to the allowable deviation from the nominal capacitance value. The "G" in the part number typically indicates a tolerance of ±2%. This relatively tight tolerance means that the actual capacitance of the capacitor will be within 2% of the nominal 1.8 nF value. Tight tolerance is crucial in applications where precise capacitance values are required for proper circuit operation, such as in oscillator circuits and high - frequency filters.
### 3.4 Temperature Coefficient
The temperature coefficient of the capacitor describes how the capacitance value changes with temperature. The C0805C182G3GACTU series is designed to have a stable temperature coefficient, ensuring that the capacitance remains relatively constant over a wide temperature range. This is important in applications where the operating temperature can vary significantly, such as in automotive electronics and industrial control systems.
## 4. Performance Advantages
### 4.1 Low Equivalent Series Resistance (ESR)
These capacitors typically have a low ESR, which is beneficial in many applications. Low ESR reduces power losses in the capacitor, especially in high - frequency circuits. It also helps to improve the efficiency of the circuit and reduces the generation of heat, which can extend the lifespan of the component and other nearby electronic parts.
### 4.2 High Frequency Performance
Due to their ceramic construction and low ESR, the C08
