# Introduction to the C1005X5R1C224K050BB Product Series
## 1. Overview
The C1005X5R1C224K050BB product series belongs to the category of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive components widely used in various electronic circuits, playing a crucial role in functions such as energy storage, filtering, coupling, and decoupling.
## 2. Product Naming Convention
Let's break down the product code "C1005X5R1C224K050BB" to understand its key specifications:
- **C**: Usually indicates that it is a capacitor.
- **1005**: This represents the package size. In the metric system, 1005 corresponds to a size of 1.0mm x 0.5mm. This compact size makes it suitable for applications where space is limited, such as in mobile devices, wearables, and other miniaturized electronic products.
- **X5R**: It is the dielectric type. X5R is a Class II dielectric, which offers a good balance between capacitance stability and temperature characteristics. The "X" indicates that the lower temperature limit is -55°C, and the "5" means the upper temperature limit is +85°C. The capacitance change within this temperature range is typically within ±15%.
- **1C**: This part of the code may be related to specific internal design or manufacturing process details of the capacitor, which are often proprietary information of the manufacturer.
- **224**: The capacitance value is encoded in this number. Using the standard capacitor value coding system, the first two digits (22) are the significant figures, and the third digit (4) is the multiplier. So, the capacitance value is \(22\times10^{4}\) pF, which is equal to 220,000 pF or 0.22 μF.
- **K**: It represents the tolerance of the capacitance. A "K" tolerance means ±10%. This indicates that the actual capacitance of the capacitor can vary within 10% of the nominal value (0.22 μF in this case).
- **050**: This may refer to the rated voltage of the capacitor. In this case, it could mean a rated voltage of 50V, which is the maximum voltage that the capacitor can safely withstand without significant degradation or failure.
- **BB**: This is often a suffix used by the manufacturer for additional identification, such as a specific production batch or a minor variation in the product design.
## 3. Electrical Characteristics
### Capacitance
As mentioned earlier, the nominal capacitance of the C1005X5R1C224K050BB capacitor is 0.22 μF with a tolerance of ±10%. This capacitance value is crucial for applications where precise charge storage and release are required, such as in power supply filtering circuits.
### Temperature Coefficient
Thanks to the X5R dielectric, the capacitor exhibits relatively stable capacitance over a temperature range of -55°C to +85°C. The capacitance change within this range is limited to ±15%, ensuring reliable performance in different environmental conditions.
