series introduction
# Introduction to the C0805C104K5RACTU Product Series
## 1. Overview
The C0805C104K5RACTU product series belongs to the category of ceramic capacitors. These capacitors are widely used in various electronic circuits due to their excellent electrical properties, reliability, and compact size. They play a crucial role in filtering, decoupling, coupling, and energy storage applications, making them an essential component in modern electronic devices.
## 2. Product Naming Convention
Let's break down the product code "C0805C104K5RACTU" to understand its key features:
- **C**: This typically indicates that it is a ceramic capacitor.
- **0805**: Refers to the package size of the capacitor. In the imperial system, 0805 means the capacitor has a length of 0.08 inches (2.032 mm) and a width of 0.05 inches (1.27 mm). This is a very common and standard package size, which offers a good balance between size and performance, and is suitable for surface - mount technology (SMT) assembly on printed circuit boards (PCBs).
- **C**: May represent the dielectric material type. In ceramic capacitors, different dielectric materials have different characteristics such as capacitance stability, temperature coefficient, and voltage rating.
- **104**: This is the capacitance value code. Using the standard capacitor coding system, the first two digits (10) are the significant figures, and the third digit (4) is the multiplier. So, \(10\times10^{4}\) pF = 100000 pF = 0.1 μF.
- **K**: Indicates the tolerance of the capacitance. A "K" tolerance means ±10%. This means that the actual capacitance value of the capacitor can vary within 10% of the nominal value (0.1 μF in this case). So, the actual capacitance can range from 0.09 μF to 0.11 μF.
- **5R**: This part of the code may be related to the rated voltage or other electrical characteristics specific to the manufacturer's coding system.
- **AC**: Could represent some additional features or a specific series within the product line, perhaps related to the application or performance characteristics.
- **TU**: May be a manufacturing - specific code, such as a particular production batch or a specific version of the product.
## 3. Electrical Characteristics
### Capacitance
As mentioned earlier, the nominal capacitance of the C0805C104K5RACTU series is 0.1 μF with a tolerance of ±10%. This capacitance value is suitable for a wide range of applications, such as bypassing high - frequency noise in power supply lines and coupling signals between different stages of an amplifier circuit.
### Voltage Rating
The rated voltage of the capacitor is an important parameter. It determines the maximum voltage that the capacitor can withstand without experiencing breakdown or significant degradation in performance. The specific voltage rating for the C0805C104K5RACTU series is indicated by the "5R" in the product code. This voltage rating ensures that the capacitor can operate safely in circuits with appropriate voltage levels.
### Temperature Coefficient
Ceramic capacitors have different temperature coefficients depending on the dielectric material used. The temperature coefficient affects how the capacitance value changes with temperature. A stable temperature coefficient is crucial in applications where the circuit performance needs to remain consistent over a wide temperature range. The C0805C104K5RACTU series is designed to have a suitable temperature coefficient to meet the requirements of various operating environments.
