series introduction
# Introduction to the T491C106M025AT Product Series
## 1. Overview
The T491C106M025AT belongs to a specialized product series, typically within the realm of electronic components. This series is designed to meet specific electrical requirements in a wide range of applications, from consumer electronics to industrial control systems.
## 2. Product Nomenclature
Let's break down the product code "T491C106M025AT" to understand its key features:
- **T491**: This is likely a series identifier assigned by the manufacturer. It represents a particular family of products with common design characteristics and performance parameters.
- **C**: This may indicate a specific capacitor type or a particular category within the T491 series. For example, it could refer to a certain dielectric material or construction style.
- **106**: In the context of capacitors, this is a common way to denote the capacitance value. Using the standard capacitor code, 106 means \(10\times10^{6}\) picofarads (pF), which is equivalent to 10 microfarads (\(\mu F\)).
- **M**: This is the tolerance code. In capacitor specifications, "M" typically represents a tolerance of ±20%. So, the actual capacitance of the T491C106M025AT can vary between 8 μF and 12 μF.
- **025**: This usually indicates the rated voltage of the component. In this case, it likely means 25 volts. So, the capacitor is designed to operate safely at a maximum voltage of 25 volts.
- **AT**: These letters may be additional codes specific to the manufacturer, perhaps indicating a particular packaging type, a special manufacturing process, or a specific version within the series.
## 3. Electrical Characteristics
### Capacitance
As mentioned earlier, the nominal capacitance of the T491C106M025AT is 10 μF with a tolerance of ±20%. This capacitance value is crucial for applications where energy storage and release are required, such as in power supply filtering circuits. A larger capacitance can store more charge and help smooth out voltage fluctuations.
### Voltage Rating
With a rated voltage of 25 volts, this component is suitable for use in low - to medium - voltage circuits. It can handle electrical stress up to this voltage level without significant degradation in performance or risk of breakdown. However, it is important to ensure that the actual operating voltage in the circuit does not exceed this rating to avoid damage to the capacitor.
### Equivalent Series Resistance (ESR)
The ESR of the T491C106M025AT is an important parameter, especially in high - frequency applications. A low ESR value indicates that the capacitor can charge and discharge quickly, reducing power losses and improving the efficiency of the circuit. The manufacturer typically provides the ESR value in the product datasheet, which can vary depending on factors such as temperature and frequency.
### Temperature Coefficient
The performance of the T491C106M025AT can be affected by temperature. The temperature coefficient indicates how the capacitance value changes with temperature. A stable temperature coefficient ensures that the capacitor maintains its electrical characteristics over a wide temperature range, making it suitable for use in environments with varying temperatures.
