series introduction

# Introduction to the C1206Y222K1RACTU Product Series

## 1. Overview
The C1206Y222K1RACTU product series belongs to the category of ceramic capacitors. These capacitors are essential passive electronic components widely used in various electronic circuits to store and release electrical energy, filter signals, and perform other crucial functions. The specific model designation "C1206Y222K1RACTU" contains important information about the capacitor's characteristics, which we will break down and explain in detail.

## 2. Physical Characteristics

### 2.1 Package Size
The "1206" in the model number refers to the package size of the capacitor. In the imperial measurement system, a 1206 package has dimensions of approximately 0.12 inches (3.2 mm) in length and 0.06 inches (1.6 mm) in width. This relatively standard size makes it compatible with a wide range of printed circuit boards (PCBs) and is suitable for both manual and automated assembly processes. The 1206 package offers a good balance between size and capacitance value, making it a popular choice in many electronic applications.

### 2.2 Construction
These capacitors are typically constructed using ceramic materials. The ceramic dielectric is sandwiched between two metal electrodes. The ceramic material used in the C1206Y222K1RACTU series is of high - quality, which provides stable electrical performance and good mechanical durability. The outer coating of the capacitor is designed to protect the internal components from environmental factors such as moisture, dust, and mechanical stress.

## 3. Electrical Characteristics

### 3.1 Capacitance Value
The "222" in the model number represents the capacitance value of the capacitor. Using the standard capacitor value coding system, the first two digits (22) are the significant figures, and the third digit (2) is the multiplier. So, the capacitance value is calculated as \(22\times10^{2}\) pF, which equals 2200 pF or 2.2 nF. This capacitance value is suitable for a variety of applications, such as coupling, decoupling, and filtering in low - to medium - frequency circuits.

### 3.2 Tolerance
The "K" in the model number indicates the tolerance of the capacitance value. A "K" tolerance means that the actual capacitance value of the capacitor can deviate from the nominal value (2.2 nF in this case) by ±10%. For example, the actual capacitance of a C1206Y222K1RACTU capacitor can range from \(2.2\times(1 - 0.1)\) nF = 1.98 nF to \(2.2\times(1 + 0.1)\) nF = 2.42 nF. This tolerance is acceptable for many general - purpose electronic circuits.

### 3.3 Voltage Rating
The "1R" in the model number represents the voltage rating of the capacitor. In this case, the voltage rating is 10 V. This means that the capacitor can safely operate in a circuit where the maximum voltage across it does not exceed 10 volts. It is important to select a capacitor with an appropriate voltage rating to ensure its reliable operation and prevent damage due to over - voltage conditions.

### 3.4 Dielectric Type
The "Y2" in the model number indicates the dielectric type of the capacitor. Y2 - type ceramic dielectrics are known for their relatively high dielectric constant, which allows for a higher capacitance value in a smaller physical size. They also have good temperature stability and are suitable for use in applications where the operating
