series introduction

# Introduction to the CL21B221KC Product Series

## Overview
The CL21B221KC product series represents a cutting - edge line of electronic components that have been engineered to meet the diverse and demanding requirements of modern electronic circuits. These components are designed with precision and high - quality materials, making them a reliable choice for a wide range of applications.

## Key Specifications
### Capacitance
The "221" in the CL21B221KC model number indicates its capacitance value. Using the standard capacitor coding system, 221 translates to a capacitance of 220 pF (picofarads). This specific capacitance value is carefully calibrated to provide the right amount of charge storage and release capabilities for various circuit designs. It allows for precise control of electrical signals, making it suitable for applications where accurate signal filtering and coupling are required.

### Tolerance
The "KC" in the model number represents the tolerance of the capacitor. In this case, it has a tolerance of ±10%. This means that the actual capacitance value of the CL21B221KC capacitor can vary within 10% of the stated 220 pF value. A relatively tight tolerance ensures that the component performs consistently within the expected range, which is crucial for maintaining the stability and accuracy of electronic circuits.

### Voltage Rating
The CL21B221KC series is designed to handle specific voltage levels. While the exact voltage rating may vary depending on the specific product within the series, it is typically rated to withstand a certain maximum voltage. This voltage rating is an important specification as it determines the maximum electrical potential difference that the capacitor can safely handle without experiencing breakdown or damage. It ensures the long - term reliability of the component in circuits where different voltage levels are present.

## Construction and Design
### Physical Dimensions
The CL21B221KC capacitors are designed with compact physical dimensions. This makes them ideal for use in printed circuit boards (PCBs) where space is often limited. Their small size allows for high - density circuit designs, enabling the integration of multiple components in a relatively small area. This is particularly beneficial in modern electronic devices such as smartphones, tablets, and wearables, where miniaturization is a key design consideration.

### Dielectric Material
These capacitors use a high - quality dielectric material. The choice of dielectric is crucial as it affects the electrical properties of the capacitor, such as its capacitance, insulation resistance, and temperature stability. The dielectric material used in the CL21B221KC series is carefully selected to provide excellent electrical performance over a wide range of operating conditions. It offers low dielectric loss, which means that less energy is dissipated as heat during the charging and discharging cycles of the capacitor. This results in improved efficiency and reliability of the overall circuit.

## Applications
### Signal Filtering
One of the primary applications of the CL21B221KC series is in signal filtering circuits. In electronic systems, unwanted noise and interference can degrade the quality of the desired signals. These capacitors can be used in combination with other passive components such as resistors and inductors to form filter circuits. The 220 pF capacitance value allows for the filtering of specific frequencies, enabling the removal of high - frequency noise while allowing the desired signals to pass through. This is commonly used in audio circuits, radio frequency (RF) circuits, and power supply filtering.

### Coupling and Decoupling
In electronic circuits, coupling capacitors are used to transfer AC signals from one stage of a circuit to another while blocking DC components. The CL21B221KC capacitors can be effectively used for this purpose. They allow the AC signals to pass through while preventing the DC bias of one stage from affecting the next. Decoupling capacitors, on the other hand, are used to provide
