series introduction
# Introduction to the C0402C223K8NACTU Product Series
## 1. Overview
The C0402C223K8NACTU product series belongs to the category of ceramic capacitors. These capacitors are widely used in various electronic circuits due to their excellent electrical properties, compact size, and high reliability. The naming convention of the product provides valuable information about its key characteristics.
### Naming Convention Breakdown
- **C0402**: This indicates the physical size of the capacitor. The 0402 size is a standard surface - mount package, with dimensions of approximately 1.0mm x 0.5mm. This small form factor makes it suitable for applications where space is at a premium, such as in mobile devices, wearable electronics, and other miniaturized electronic products.
- **C**: Usually represents the ceramic dielectric material used in the capacitor. Ceramic dielectrics offer several advantages, including high dielectric constant, low loss, and good temperature stability.
- **223**: This is the capacitance value code. Using the standard three - digit coding system, the first two digits (22) are the significant figures, and the third digit (3) is the multiplier. So, the capacitance value is \(22\times10^{3}\) pF, which is equal to 22,000 pF or 0.022 μF.
- **K**: Indicates the tolerance of the capacitance value. A "K" tolerance means that the actual capacitance value can vary by ±10% from the nominal value. For example, for a nominal capacitance of 0.022 μF, the actual capacitance can range from \(0.022\times(1 - 0.1)=0.0198\) μF to \(0.022\times(1 + 0.1)=0.0242\) μF.
- **8**: This may refer to the voltage rating or other specific electrical characteristics depending on the manufacturer's coding system.
- **NAC**: Could be a specific code related to the product's series, manufacturing process, or additional features defined by the manufacturer.
- **TU**: May represent the packaging type or other end - user - relevant information.
## 2. Electrical Characteristics
### Capacitance
As mentioned earlier, the nominal capacitance of the C0402C223K8NACTU series is 0.022 μF. This capacitance value is crucial for applications such as filtering, coupling, and bypassing in electronic circuits. In a filtering circuit, the capacitor can be used to block DC signals while allowing AC signals of a certain frequency range to pass through. For example, in a power supply filtering circuit, it can smooth out the ripples in the DC voltage by storing and releasing electrical energy.
### Tolerance
The ±10% tolerance ensures that the capacitor's performance remains within an acceptable range for most applications. However, in some precision circuits where accurate capacitance values are required, additional calibration or selection of capacitors with tighter tolerances may be necessary.
### Voltage Rating
The voltage rating (represented by the digit "8" in the naming, which needs to be confirmed with the manufacturer's documentation) determines the maximum voltage that the capacitor can safely withstand without breaking down. Exceeding the voltage rating can lead to dielectric breakdown, which may cause the capacitor to fail and potentially damage other components in the circuit.
### Temperature Coefficient
Ceramic capacitors typically have a certain temperature coefficient, which describes how the capacitance value changes with temperature. The C0402C223K8NACTU series is likely to have a relatively stable temperature coefficient, ensuring consistent performance over a wide temperature range. This is
