series introduction
# Introduction to the C3216X5R1E476M160AC Product Series
## 1. Overview
The C3216X5R1E476M160AC product series belongs to the category of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive components widely used in various electronic circuits due to their excellent electrical properties, compact size, and high reliability.
## 2. Product Naming Convention
Let's break down the product code "C3216X5R1E476M160AC" to understand its key features:
- **C**: Usually indicates that it is a capacitor.
- **3216**: This represents the physical size of the capacitor in the metric system. In this case, 3216 corresponds to a length of 3.2mm and a width of 1.6mm, which is a common size in surface - mount technology (SMT) applications. It allows for easy integration onto printed circuit boards (PCBs) using automated assembly processes.
- **X5R**: This is the dielectric type. X5R is a Class II dielectric, which offers a good balance between capacitance, temperature stability, and cost. It has a temperature range of - 55°C to +85°C, and the capacitance change within this temperature range is typically within ±15%.
- **1E**: The voltage rating is encoded here. In the EIA standard, "1E" corresponds to a rated voltage of 25V. This means the capacitor can safely operate in circuits where the voltage does not exceed 25V.
- **476**: This indicates the capacitance value. Using the standard capacitor value coding system, the first two digits (47) are the significant figures, and the third digit (6) is the multiplier. So, the capacitance value is \(47\times10^{6}\) pF, which is equivalent to 47 μF.
- **M**: The tolerance of the capacitance is denoted by this letter. "M" represents a tolerance of ±20%. This means that the actual capacitance of the capacitor can vary between 37.6 μF (47 μF - 20% of 47 μF) and 56.4 μF (47 μF+ 20% of 47 μF).
- **160**: This may be a specific code related to the manufacturer's internal specifications, such as a particular batch or production line.
- **AC**: This could also be a manufacturer - specific code, perhaps indicating a certain feature or application suitability.
## 3. Electrical Characteristics
### Capacitance
With a nominal capacitance of 47 μF, these capacitors can store a relatively large amount of electrical charge. This makes them suitable for applications where energy storage and filtering are required, such as in power supply circuits to smooth out voltage fluctuations.
### Temperature Stability
Thanks to the X5R dielectric, the capacitance remains relatively stable over a temperature range of - 55°C to +85°C. This is crucial in applications where the operating environment may experience temperature variations, ensuring consistent performance of the electronic circuit.
### Voltage Rating
The 25V voltage rating allows the capacitor to be used in a wide range of low - to medium - voltage circuits. It can handle the normal voltage levels found in many consumer electronics, industrial control systems, and communication devices.
### Equivalent Series Resistance (ESR)
MLCCs in this series typically have a relatively low ESR. A low ESR is beneficial as it reduces power losses in the capacitor, especially in high - frequency applications. It also helps in improving the efficiency of the circuit and reducing the generation
