Resistor Networks, Arrays

The YC358LJK-07180RL is a four resistor network that functions as a three-terminal potentiometer. It has resistance values of 5 kΩ, 10 kΩ, 20 kΩ, and 40 kΩ, each split into 1/2 increments along the resistor array. It has a maximum voltage rating of 25V and a minimum operating temperature of -40°C. The resistance range on this network is 0 - 30 kΩ and can be connected as a variable resistor, where the terminal connected to the middle of the resistor array is the wiper terminal that determines resistance.

Application Field

The YC358LJK-07180RL is typically used as a rotary potentiometer in a variety of mechanical and electrical circuits. It can be used to control the volume of an audio device, actuate a servo motor, or adjust a heater temperature. It is also used in the automotive industry as a position sensor and in medical equipment as part of an electrocardiograph or an electroencephalograph.

Working Principle

The YC358LJK-07180RL consists of four resistors connected in series to form a single resistor array. The middle terminal is connected to the wiper, which slides along the resistor array as it is adjusted to increase or decrease resistance. This arrangement allows for resolution down to 1/2 increment movements along the network. When connected in the resistive divider configuration, the opposite and wiper terminals of the resistor network are connected to a voltage source. The voltage is then divided proportionally between the resistors and the wiper, allowing for the adjustment of the resistance and the output voltage.

Conclusion

The YC358LJK-07180RL resistor network is an excellent choice for applications that require precise and accurate resistance values. Its wide resistance range and 1/2 increment resolution makes it a great solution for applications that require fine turning, such as controlling the volume of an audio device or adjusting the temperature of a heater.
