series introduction
# Introduction to the GRM188R71E223KA01 Product Series
## 1. Overview
The GRM188R71E223KA01 belongs to a high - performance series of multilayer ceramic capacitors (MLCCs). These components are widely used in various electronic circuits due to their excellent electrical properties, compact size, and high reliability. MLCCs are essential building blocks in modern electronics, and the GRM188R71E223KA01 series offers specific features that make it suitable for a range of applications.
## 2. Product Naming Convention
Let's break down the product code "GRM188R71E223KA01" to understand its key characteristics:
- **GRM**: This is the product series prefix, which is a common identifier for a particular line of MLCCs from the manufacturer. It represents a specific design and manufacturing process that ensures consistent quality and performance.
- **188**: Indicates the size of the capacitor. In this case, it typically refers to the physical dimensions of the component. The specific size is important as it determines how the capacitor can be integrated into a printed circuit board (PCB) layout.
- **R7**: This denotes the dielectric type. The R7 dielectric is a Class II dielectric, which offers a relatively high capacitance value for a given size. It has a temperature coefficient that is suitable for many general - purpose applications where the capacitance may vary within an acceptable range with temperature changes.
- **1E**: Represents the rated voltage of the capacitor. In this case, the rated voltage is 25V. The rated voltage is a crucial parameter as it determines the maximum voltage that the capacitor can safely withstand without experiencing breakdown or other reliability issues.
- **223**: This is the capacitance value code. Using the standard three - digit code for MLCCs, the first two digits (22) are the significant figures, and the third digit (3) is the multiplier. So, the capacitance value is \(22\times10^{3}\) pF, which is equivalent to 22 nF.
- **KA**: Indicates the tolerance of the capacitance. The "KA" code typically represents a tolerance of ±10%. This means that the actual capacitance value of the capacitor can vary by up to 10% from the nominal value of 22 nF.
- **01**: This may be a specific version or manufacturing code that the manufacturer uses for internal tracking and quality control purposes.
## 3. Electrical Characteristics
### Capacitance
As mentioned earlier, the nominal capacitance of the GRM188R71E223KA01 is 22 nF with a tolerance of ±10%. This capacitance value is suitable for a variety of filtering, coupling, and bypass applications in electronic circuits. For example, in power supply circuits, it can be used to filter out high - frequency noise and provide a stable DC voltage to the load.
### Voltage Rating
With a rated voltage of 25V, the capacitor can be used in circuits where the operating voltage does not exceed this value. It is important to ensure that the voltage across the capacitor in the actual application is within the rated voltage to avoid premature failure. In some low - voltage DC - DC converter circuits or battery - powered devices, this voltage rating is sufficient to handle the normal operating conditions.
### Temperature Coefficient
The R7 dielectric has a temperature coefficient that allows the capacitance to vary within a certain range as the temperature changes. This is important in applications where the operating temperature may fluctuate. For example, in automotive electronics or industrial control systems, the capacitor needs to maintain its performance over a wide temperature range.
