The digital control also eliminates the problems associated with mechanical wear and tear, such as contact oxidation and mechanical jitter, ensuring long - term stability and reliability.
### 2.2 Resistance Value
The "104" in the product code indicates a nominal resistance value of 100 kΩ. This resistance value is suitable for a variety of applications, including signal conditioning, voltage division, and impedance matching. The potentiometer offers a wide range of resistance adjustment, allowing designers to fine - tune the electrical characteristics of their circuits with high precision.
### 2.3 Low Temperature Coefficient
The MCP4017T - 104E/LT series has a low temperature coefficient of resistance (TCR). This means that the resistance value of the potentiometer changes very little with temperature variations. In applications where temperature stability is crucial, such as in precision measurement equipment and temperature - sensitive circuits, this feature ensures accurate and consistent performance over a wide temperature range.
### 2.4 Small Package Size
These digital potentiometers are available in a compact package, which is beneficial for space - constrained applications. The small form factor allows for easy integration into printed circuit boards (PCBs) with limited real estate, making them ideal for use in portable devices, miniaturized electronics, and other applications where size is a critical factor.
### 2.5 Low Power Consumption
The MCP4017T - 104E/LT series is designed to consume very low power. This is an important consideration in battery - powered devices and energy - efficient applications. By minimizing power consumption, the potentiometers help to extend the battery life of the device and reduce overall energy costs.
