series introduction
# Introduction to the C1608X5R0J226M Product Series
## 1. Overview
The C1608X5R0J226M product series belongs to the category of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive electronic components widely used in various electronic circuits for functions such as energy storage, filtering, coupling, and decoupling. Their compact size, high performance, and reliability make them a popular choice in modern electronic devices.
## 2. Product Naming Convention
Let's break down the product code “C1608X5R0J226M” to understand its key specifications:
- **C**: Usually indicates that it is a capacitor.
- **1608**: This refers to the capacitor's package size. In the metric system, 1608 corresponds to a length of 1.6 mm and a width of 0.8 mm. This small form - factor is suitable for applications where space is limited, such as in mobile devices, wearable electronics, and compact circuit boards.
- **X5R**: It represents the dielectric type. X5R is a Class II dielectric, which offers a good balance between capacitance stability, temperature coefficient, and cost. The “X” indicates that the capacitor can operate in a temperature range from - 55°C to +85°C. The “5” represents the maximum temperature coefficient of capacitance, which is ±15% over the specified temperature range.
- **0J**: The “0” is often a placeholder or part of the internal coding of the manufacturer. The “J” indicates the tolerance of the capacitance value. In this case, a “J” tolerance means ±5%.
- **226**: This is the capacitance value code. Using the standard capacitor coding system, the first two digits (22) are the significant figures, and the third digit (6) is the multiplier. So, the capacitance value is \(22\times10^{6}\) pF, which is equivalent to 22 μF.
- **M**: It represents the voltage rating. The specific voltage value corresponding to “M” depends on the manufacturer's coding system, but it typically indicates a certain standard voltage level for the capacitor.
## 3. Electrical Characteristics
### Capacitance
With a nominal capacitance of 22 μF, the C1608X5R0J226M capacitor can store a relatively large amount of electrical charge. This makes it suitable for applications where significant energy storage is required, such as in power supply filtering circuits to smooth out voltage fluctuations.
### Tolerance
The ±5% tolerance ensures that the actual capacitance value of the capacitor will be within 5% of the nominal 22 μF value. This high - precision tolerance is important in circuits where accurate capacitance values are crucial for proper operation, such as in resonant circuits or precision filtering applications.
### Temperature Coefficient
Thanks to the X5R dielectric, the capacitor maintains a relatively stable capacitance within the temperature range of - 55°C to +85°C. The ±15% change in capacitance over this temperature range is acceptable for many general - purpose applications. However, in more temperature - sensitive circuits, additional compensation or selection of a different dielectric type may be required.
### Voltage Rating
The voltage rating indicated by the “M” code determines the maximum voltage that the capacitor can safely withstand without experiencing breakdown or other reliability issues. It is important to select a capacitor with an appropriate voltage rating for the specific application to ensure long - term stability and safety.
