# Introduction to the CM105X5R475K06AT Product Series
## 1. Overview
The CM105X5R475K06AT product series belongs to the category of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive components widely used in various electronic circuits to store and release electrical energy, filter signals, and stabilize voltage levels. The specific model CM105X5R475K06AT is designed to meet the demanding requirements of modern electronic applications with its unique combination of electrical characteristics, physical dimensions, and reliability.
## 2. Product Naming Convention
Let's break down the model number CM105X5R475K06AT to understand its key features:
- **CM**: This is likely the manufacturer's code or a specific product line identifier assigned by the company. It helps in differentiating the products from different manufacturers or within the same manufacturer's portfolio.
- **105**: This represents the capacitance value. In the capacitor naming convention, the first two digits are significant figures, and the third digit is the multiplier. So, for 105, the significant figures are 10, and the multiplier is \(10^5\). The capacitance is calculated as \(10\times10^5\) pF, which is equal to 1 μF.
- **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 coefficient of ±15% over a temperature range of -55°C to +85°C. This means that the capacitance value of the capacitor will remain within ±15% of its nominal value within this temperature range.
- **475**: This is another way of indicating the capacitance value, which is consistent with the previous calculation.
- **K**: This represents the tolerance of the capacitance. A "K" tolerance means ±10%. So, the actual capacitance of the CM105X5R475K06AT capacitor can vary between 0.9 μF (1 μF - 10%) and 1.1 μF (1 μF + 10%).
- **06**: This might refer to the package size or the case code of the capacitor. Different package sizes are used to accommodate different circuit board layouts and application requirements.
- **AT**: This could be a specific suffix indicating additional features, such as a particular termination material, manufacturing process, or compliance with certain industry standards.
## 3. Electrical Characteristics
### Capacitance
As mentioned earlier, the nominal capacitance of the CM105X5R475K06AT is 1 μF with a tolerance of ±10%. This capacitance value is crucial for applications such as decoupling, where the capacitor is used to provide a local reservoir of electrical energy to smooth out voltage fluctuations in a circuit.
### Voltage Rating
The capacitor is designed to operate at a specific voltage rating. While the model number does not explicitly mention the voltage rating, it is typically specified in the product datasheet. Common voltage ratings for MLCCs range from a few volts to several hundred volts. The voltage rating determines the maximum voltage that the capacitor can safely withstand without experiencing dielectric breakdown.
### Temperature Coefficient
The X5R dielectric provides a temperature coefficient of ±15% over the temperature range of -55°C to +85°C. This makes the CM105X5R475K06AT suitable for applications where the operating temperature may vary within this range, such as automotive electronics, industrial control systems, and consumer electronics.
