series introduction
# Introduction to the C1005X7R1E103K050BB Product Series
## 1. Overview
The C1005X7R1E103K050BB 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 to understand its key features:
- **C**: This typically indicates that it is a capacitor.
- **1005**: Refers to the physical size of the capacitor, also known as the 0402 imperial size. In metric units, it has a length of 1.0 mm and a width of 0.5 mm. This small size makes it suitable for applications where space is limited, such as in mobile devices, wearable electronics, and other miniaturized electronic products.
- **X7R**: This is the dielectric type. X7R is a Class II dielectric, which offers a good balance between capacitance stability and temperature coefficient. It has a temperature range of -55°C to +125°C, and the capacitance change within this temperature range is relatively small (±15%). This makes it suitable for a wide range of operating environments.
- **1E**: The "1E" represents the voltage rating. In the EIA standard, "1E" corresponds to a voltage rating of 25V. This means the capacitor can safely operate at a maximum DC voltage of 25 volts.
- **103**: 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 (3) is the multiplier. So, the capacitance value is \(10\times10^{3}\) pF, which is equal to 10,000 pF or 0.01 μF.
- **K**: Indicates the tolerance of the capacitance value. A "K" tolerance means ±10%. So, the actual capacitance of the capacitor can vary between 9,000 pF (0.009 μF) and 11,000 pF (0.011 μF).
- **050**: This may be a specific code related to the manufacturer's internal specifications, such as a particular batch or production line.
- **BB**: It could also be a manufacturer - specific code, perhaps related to the packaging type or additional product features.
## 3. Electrical Characteristics
### Capacitance
As mentioned earlier, the nominal capacitance of the C1005X7R1E103K050BB is 0.01 μF with a tolerance of ±10%. This capacitance value is crucial for applications such as filtering, coupling, and bypassing in electronic circuits. For example, in a power supply circuit, it can be used as a bypass capacitor to filter out high - frequency noise and provide a stable power supply to the components.
### Voltage Rating
With a voltage rating of 25V, the capacitor can handle electrical stress up to this level without significant degradation in performance or risk of breakdown. It is important to ensure that the operating voltage in the circuit does not exceed this rating to avoid damage to the capacitor.
### Temperature Coefficient
Thanks to the X7R dielectric, the capacitor has a relatively stable capacitance over a wide temperature range from -55°C to +125°C. This makes it suitable for use in both high - and low - temperature environments, such as automotive electronics, industrial control systems, and aerospace applications.
