CL21B223KCFNNNE Series

series introduction

# Introduction to the CL21B223KCFNNNE Product Series

## 1. Overview
The CL21B223KCFNNNE product series belongs to the category of multilayer ceramic capacitors (MLCCs). These components are essential building - blocks in modern electronic circuits, offering a reliable and efficient solution for a wide range of applications. MLCCs are known for their small size, high capacitance values, and excellent electrical performance, and the CL21B223KCFNNNE series is no exception.

## 2. Product Naming Convention
Let's break down the meaning of the product code "CL21B223KCFNNNE":
- **CL**: This is often a prefix specific to the manufacturer, which helps in identifying the product line and the brand.
- **21**: Usually represents the size or the case code of the capacitor. In the industry - standard EIA (Electronic Industries Alliance) system, different numbers correspond to specific physical dimensions. A "21" might indicate a particular length - width combination, which is crucial for PCB (Printed Circuit Board) layout design.
- **B**: This could be related to the dielectric material used in the capacitor. Different dielectric materials have different characteristics such as temperature coefficient, voltage rating, and stability.
- **223**: This is a code for the capacitance value. In the three - digit notation commonly used for MLCCs, the first two digits are the significant figures, and the third digit is the multiplier. So, "223" means \(22\times10^{3}\) picofarads (pF), which is equivalent to 22,000 pF or 0.022 microfarads (\(\mu F\)).
- **K**: Represents the tolerance of the capacitance value. A "K" indicates a tolerance of ±10%. This means that the actual capacitance of the capacitor can vary within 10% of the nominal value (22,000 pF in this case).
- **CF**: This part of the code may be related to additional features or performance characteristics, such as the type of termination or the operating temperature range.
- **NNNE**: These characters are likely to be a unique identifier for the specific product version, batch, or other manufacturer - specific details.

## 3. Electrical Characteristics

### Capacitance
As mentioned earlier, the nominal capacitance of the CL21B223KCFNNNE series is 0.022 \(\mu F\). This capacitance value is suitable for a variety of applications, including decoupling, filtering, and coupling in electronic circuits. Decoupling capacitors are used to provide a local reservoir of charge to smooth out voltage fluctuations in power supply lines, while coupling capacitors are used to transfer AC signals between different stages of a circuit while blocking DC components.

### Tolerance
With a ±10% tolerance, the actual capacitance of the capacitor can range from \(0.022\times(1 - 0.1)=0.0198\ \mu F\) to \(0.022\times(1 + 0.1)=0.0242\ \mu F\). This level of tolerance is acceptable for many general - purpose applications where precise capacitance values are not critical. However, in applications such as high - frequency oscillators or precision filters, a tighter tolerance may be required.

### Voltage Rating
The voltage rating of the CL21B223KCFNNNE series is an important parameter. It indicates the maximum voltage that the capacitor can withstand without experiencing breakdown or significant degradation in performance. The specific voltage rating of this series would be provided in the product datasheet, and it can range from a few volts to several
