Resistor Networks, Arrays are composed of two or more discrete resistors connected in various ways to form a desired network. Depending on their application, networks may also contain flux capacitors, inductors, and other components to form a suitable circuit. The 4116R-1-221 is a very specific resistor network of this kind. It is made for applications in electronic circuits and primarily used for thermistor, temperature sensing, or thermal stability applications.

The 4116R-1-221 network contains two resistors and a single trimmer connected in series. The two resistors are single-turn linear with a standard value of 100 ohms for both of them and a tolerance of 5%. The trimmer is a twin-layer conductive pattern having a total resistance of 1000 ohms, with a single-turn linearity of 1 ohm and 5% tolerance. All three resistors are connected in series and the junction point provides the output voltage of the network. This allows its thermistor applications to be done without a differential amplifier as the voltage drops will be detected immediately.

In thermistor applications, the 4116R-1-221 network can be used as a temperature sensor or as a temperature controlled voltage regulator. The temperature itself is processed into an equivalent voltage which is then supplied to the input of the network. The 100 ohm resistor works as the base resistor for the trimmer, and as temperature rises the trimmer resistance decreases. This in turn increases the voltage of the output and the amount of voltage change is directly proportional to the temperature change.

The 4116R-1-221 network is also suitable for thermal stability applications. When used as a thermal stabilizer, the output voltage is held constant regardless of temperature changes. The trimmer in this application plays the role of a feedback resistor in the network, and its resistance is dependent on the input voltage. As temperatures rise, the resistance of the trimmer changes and maintains a constant feedback which keeps the voltage of the output stable.

Additionally, the 4116R-1-221 network can be used in circuits that require protection from temperature drops. As the temperature drops, the resistance of the trimmer increases which prevents voltage from dropping. This helps to avoid the possibility of over voltage, providing an extra layer of protection for electrical systems.

Overall, the 4116R-1-221 network is a convenient and versatile device with a wide range of applications. Its ability to provide a consistent voltage output, in a single package, makes it a great choice for temperature sensing and thermal stabilizing electronic circuits. It also provides efficient and reliable protection from temperature fluctuations and over voltage. All of these features make the 4116R-1-221 network a great choice for any project.
