series introduction
# Introduction to the C1206C472J5RACTU Product Series
## 1. Overview
The C1206C472J5RACTU 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 "C1206C472J5RACTU" to understand its key specifications:
- **C**: This typically indicates that it is a ceramic capacitor.
- **1206**: Refers to the package size of the capacitor. In the imperial system, a 1206 package has dimensions of 0.12 inches (length) by 0.06 inches (width), which is approximately 3.2mm x 1.6mm. This standard size makes it compatible with a wide range of printed circuit boards (PCBs) and surface - mount technology (SMT) assembly processes.
- **C**: May represent the dielectric type. In this case, it often indicates a Class 1 ceramic dielectric, which offers high stability and low loss characteristics.
- **472**: 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 (2) is the multiplier. So, the capacitance value is \(47\times10^{2}\) pF, which equals 4700 pF or 4.7 nF.
- **J**: Represents the tolerance of the capacitance. A "J" tolerance means ±5%, indicating that the actual capacitance of the capacitor can vary within 5% of the nominal value (4.7 nF in this case).
- **5R**: This might be related to additional electrical or mechanical characteristics specific to the manufacturer's internal coding. It could indicate a certain voltage rating or other performance - related parameters.
- **AC**: Could be part of the manufacturer's series or product line identifier.
- **TU**: May represent the packaging type or other special features defined by the manufacturer.
## 3. Electrical Characteristics
### Capacitance
As mentioned earlier, the nominal capacitance of the C1206C472J5RACTU series is 4.7 nF with a tolerance of ±5%. This relatively small capacitance value makes it suitable for high - frequency applications where precise capacitance values are required.
### Voltage Rating
The voltage rating of these capacitors 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 C1206C472J5RACTU series would be specified by the manufacturer, and it is crucial to select a capacitor with an appropriate voltage rating for the intended application to ensure reliable operation.
### Dielectric Constant and Loss Tangent
Since it is likely a Class 1 ceramic dielectric, these capacitors typically have a relatively low dielectric constant compared to Class 2 ceramics. However, they offer excellent stability over a wide range of temperatures and frequencies. The low loss tangent of Class 1 ceramics means that they dissipate very little energy as heat, making them ideal for applications where low power loss is critical, such as in high - frequency oscillators and filters.
### Temperature Coefficient
Class 1 ceramic capacitors usually have a well - defined temperature coefficient. This indicates how the capacitance value changes with temperature. For example, some Class 1 ceramics may have a temperature coefficient of ±30 ppm/°C, which means that for every
