series introduction
# Introduction to the CC0805KKX7R6BB475 Product Series
## 1. Overview
The CC0805KKX7R6BB475 product series belongs to the category of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive electronic components widely used in various electronic circuits for functions such as energy storage, filtering, coupling, and decoupling. The specific model number CC0805KKX7R6BB475 contains a wealth of information about the capacitor's characteristics and specifications.
## 2. Physical Characteristics
### Package Size
The "0805" in the model number indicates the package size of the capacitor. In the imperial measurement system, an 0805 package has dimensions of approximately 0.08 inches (2.032 mm) in length and 0.05 inches (1.27 mm) in width. This relatively compact size makes it suitable for use in printed circuit boards (PCBs) where space is at a premium, such as in mobile devices, wearable electronics, and small - form - factor consumer electronics.
### Construction
These MLCCs are constructed by stacking multiple layers of ceramic dielectric material and internal electrodes. The ceramic dielectric is typically made of a ferroelectric material, which provides high dielectric constant and good electrical properties. The internal electrodes are usually made of metals such as nickel or copper, and they are arranged in an interleaved pattern to form the capacitor structure. The entire assembly is then encapsulated in a protective ceramic or plastic housing to ensure mechanical stability and protection from environmental factors.
## 3. Electrical Characteristics
### Capacitance
The "475" in the model number represents the capacitance value of the capacitor. Using the standard capacitor value coding system, the first two digits (47) are the significant figures, and the third digit (5) is the multiplier. So, the capacitance value is \(47\times10^{5}\) picofarads (pF), which is equivalent to 4.7 microfarads (\(\mu F\)). This relatively high capacitance value makes the CC0805KKX7R6BB475 suitable for applications that require large amounts of charge storage or filtering of low - frequency signals.
### Dielectric Type
The "X7R" indicates the dielectric type of the capacitor. X7R is a Class II dielectric, which offers a good balance between capacitance, temperature stability, and cost. 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 vary within ±15% of its nominal value over this temperature range, making it suitable for a wide range of operating environments.
### Voltage Rating
The "6" in the model number is related to the voltage rating of the capacitor. In this case, it typically indicates a voltage rating of 6.3 volts (V). This voltage rating specifies the maximum DC or peak AC voltage that the capacitor can withstand without experiencing breakdown or significant degradation of its electrical properties. It is important to select a capacitor with an appropriate voltage rating for the specific application to ensure reliable operation.
### Tolerance
The "K" in the model number represents the capacitance tolerance. A "K" tolerance means that the actual capacitance value of the capacitor can deviate from the nominal value by ±10%. This tolerance level is common in many general - purpose applications and provides a reasonable balance between cost and accuracy.
