4310R-102-221

Resistor networks, arrays, such as 4310R-102-221, are components containing multiple resistors joined together. They are usually used in electronics circuits to provide specific electrical resistances in a convenient way instead of using multiple discrete resistors. Additionally, networks may contain components other than resistors such as capacitors and inductors in the same package. Networks offer a few advantages such as improved reliability due to less space on the circuit board being occupied, and greater protection from electrical noise and interference.

By definition, 4310R-102-221 is a 4 terminal resistor network composed of three fixed resistors connected in series. Its primary purpose is to provide an adjustable resistance in a compact package. The resistance values are adjustible by moving a movable contact (screw, contact, or thumbwheel) across the fixed resistors.

The 4310R-102-221 network has two terminals in the center which connects to the movable contacts while the other two terminals are connected to the resistors. The adjustable resistance range is between 10K ohms and 21K ohms. It comes in a 0.877" square package body with 8-32 mounting holes.

The working principle of 4310R-102-221 is very simple. When the movable contact is located at the left terminal, the resistance between the two right terminals is 10K ohms. Similarly, when the movable contact is located at the right terminal, the resistance between the two left terminals is 21K ohms. As the movable contact is moved to different places between left and right terminals, the resistance value changes accordingly.

The application field of 4310R-102-221 is widespread. It can be used in a wide range of applications from robotics, energy measurement and control, audio and video applications, and medical instrumentation, to name a few. For example, in robotics the adjustable resistors can be used to accurately control speed, direction, and conditioning of motors. In audio and video applications, they can be used to control the level of audio intput and output devices. In energy measurement and control, they can be used to measure the amount of energy being used by a device or system.

In summary, 4310R-102-221 is a resistor network consisting of three fixed resistors connected in series and provides an adjustable resistance across two terminals. The adjustable resistance range is between 10K ohms and 21K ohms. It is widely used in various applications ranging from robotics and energy control to audio and video. Its working principle is based on the adjustment of the movable contact to control the resistance value across the two terminals.
