series introduction
# Introduction to the CC0402KRX7R9BB471 Product Series
## 1. Overview
The CC0402KRX7R9BB471 belongs to a highly specialized and widely - used series of electronic components, specifically ceramic capacitors. These capacitors play a crucial role in modern electronic circuits, providing essential functions such as energy storage, filtering, coupling, and decoupling. The "CC" likely represents the manufacturer's product line identifier, while the "0402" refers to the industry - standard package size, which is compact and suitable for a variety of high - density circuit board designs.
## 2. Package Size (0402)
The 0402 package is a surface - mount device (SMD) package with specific dimensions. In the metric system, it measures approximately 1.0mm x 0.5mm. This small size makes it ideal for applications where space is at a premium, such as in mobile devices, wearables, and other miniaturized electronic products. The compact nature of the 0402 package also allows for high - density placement on printed circuit boards (PCBs), enabling the design of more complex and integrated circuits.
## 3. Dielectric Material (X7R)
The "X7R" indicates the type of dielectric material used in the capacitor. X7R is a Class II ceramic dielectric, which offers several advantages. It has a relatively high dielectric constant, which means it can store a significant amount of electrical charge in a small volume. This makes the CC0402KRX7R9BB471 suitable for applications that require high capacitance values in a compact form factor.
Another important characteristic of X7R dielectric is its temperature stability. It has a temperature coefficient of capacitance (TCC) of ±15% over a temperature range of - 55°C to +125°C. This means that the capacitance value of the capacitor will remain relatively stable within this temperature range, ensuring reliable performance in a wide variety of environmental conditions.
## 4. Capacitance Value (471)
The "471" in the product code represents the capacitance value of the capacitor. In the capacitor coding system, the first two digits (47) are the significant figures, and the third digit (1) is the multiplier. So, the capacitance value is calculated as 47 x 10^1 pF, which equals 470 pF. This capacitance value is well - suited for a range of applications, including high - frequency filtering, coupling between different stages of an amplifier circuit, and decoupling power supplies to reduce noise and interference.
## 5. Tolerance (K)
The "K" indicates the tolerance of the capacitance value. A "K" tolerance means that the actual capacitance value of the capacitor can vary by ±10% from the nominal value. For example, for a CC0402KRX7R9BB471 capacitor with a nominal capacitance of 470 pF, the actual capacitance can range from 423 pF (470 pF - 10% of 470 pF) to 517 pF (470 pF+ 10% of 470 pF). This tolerance level is acceptable for many general - purpose applications, but for more precise circuits, capacitors with tighter tolerances may be required.
## 6. Voltage Rating (9B)
The "9B" in the product code is related to the voltage rating of the capacitor. The specific voltage rating can be determined by referring to the manufacturer's datasheet. Generally, the voltage rating indicates the maximum voltage that the capacitor can withstand without experiencing breakdown or other forms of failure.
