RAVF104DFT680K

Resistor Networks, Arrays

RAVF104DFT680K is a common reliable residential component that is used in consumer electronics. It is a resistor array that has series connected five 0.1 ohm resistors along with single 680 ohm resistor. This 680 ohm resistor is adjustable and is referred as R3 in the circuit diagram. The series combination of five 0.1 ohm resistors is referred as R1 in the circuit.

The RAVF104DFT680K can be used to extend the fan speed controlled operations in most modern electronic appliances. For this purpose, the five 0.1 ohm resistors (R1) are connected in series and the 680 ohm resistor (R3) is connected in parallel to them. As the fan speed increases, a very small current is passed through R3, thus reducing the voltage drop across the resistor. By varying the number of 0.1 ohm resistors and the current, the fan operating parameters can be adjusted as desired.

The 0.1 ohm resistors are also used to adjust the circuit parameters to maintain consistent temperature levels within the appliance. When the coefficient of resistivity increases due to temperature fluctuations in the environment, the 0.1 ohm resistors form the basis of the resistor network. As the resistivity of air increases, more current is drawn through the resistor network, thus compensating for the changes in temperature.

The RAVF104DFT680K can be used in many other applications. It is often found in higher speed motor applications such as in power supplies or low voltage applications like LED lighting. The 680 ohm resistor (R3) is adjustable to provide precise and settled current control for higher power and current applications. It also helps to reduce the power losses in these applications when compared to a fixed resistor.

The RAVF104DFT680K can also be used in communication equipment. The adjustable resistor allows one to accurately control the signal or audio path parameters without any distortion or misdirection. Additionally, its design provides high noise immunity and reliability.

Overall, the RAVF104DFT680K is an invaluable residential component that can be used in multiple applications. Its adjustable resistor (R3) allows for precise current control while its 0.1 ohm resistors (R1) allow for temperature compensation and stability. Its properties make it an excellent choice for many consumer electronics, motor applications, power supplies, LED lighting and communication equipment.
