series introduction
# Introduction to the C1210C473J5RAC Product Series
## 1. Overview
The C1210C473J5RAC 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 series is designed to meet the demanding requirements of modern electronic applications with its specific electrical characteristics and physical properties.
## 2. Naming Convention
Let's break down the product code "C1210C473J5RAC" to understand its key features:
- **C**: This typically indicates that it is a ceramic capacitor. Ceramic capacitors are known for their high dielectric constant, which allows for relatively high capacitance values in a small package.
- **1210**: Refers to the physical size of the capacitor, also known as the package size. In the imperial system, a 1210 package has dimensions of 0.12 inches (length) by 0.10 inches (width). This size is relatively common in surface - mount technology (SMT) applications, offering a good balance between capacitance and board space utilization.
- **C**: This may represent a specific dielectric type. Different dielectric materials have different properties such as temperature coefficient, voltage rating, and stability.
- **473**: The capacitance value is encoded in this part of the code. The first two digits (47) are the significant figures, and the third digit (3) is the multiplier. So, the capacitance value is \(47\times10^{3}\) picofarads (pF), which is equivalent to 47 nanofarads (nF).
- **J**: Indicates the tolerance of the capacitance value. A "J" tolerance means ±5%. This means that the actual capacitance of the capacitor can vary within 5% of the nominal value (47 nF in this case).
- **5R**: This might be related to the voltage rating or other electrical characteristics specific to the manufacturer's coding system.
- **AC**: Could represent additional features, such as the type of application or a specific series within the product line.
## 3. Electrical Characteristics
### Capacitance
As mentioned earlier, the nominal capacitance of the C1210C473J5RAC series is 47 nF with a tolerance of ±5%. This capacitance value is suitable for a variety of applications, including filtering out high - frequency noise in power supply lines and coupling signals between different stages of an amplifier circuit.
### Voltage Rating
The voltage rating of the capacitor is an important parameter that determines the maximum voltage it can withstand without breaking down. The specific voltage rating associated with the "5R" in the part number would need to be obtained from the manufacturer's datasheet. Common voltage ratings for ceramic capacitors in this size range can be 16V, 25V, 50V, etc.
### Temperature Coefficient
The temperature coefficient of the dielectric material affects how the capacitance value changes with temperature. Different dielectric types have different temperature coefficients, which can range from positive to negative. A stable temperature coefficient is important in applications where the performance of the circuit needs to remain consistent over a wide temperature range.
### Equivalent Series Resistance (ESR)
ESR is the resistance that appears in series with the capacitance. A low ESR is desirable in many applications, especially in power supply filtering, as it reduces power losses and improves the efficiency of the circuit. The ESR of the C1210C473J5RAC series would be specified in the datasheet and is typically in the milliohm range for high - quality ceramic capacitors.
