Oscillators are electronic components commonly used in many industrial applications. While there are different types of oscillators, SIT1602BC-82-28N-12.000000T (hereafter referred to as SIT) is a particular type of oscillator that is used in many industrial applications. In this article, the application field and working principle of SIT will be discussed.

SITs are typically used in applications where relatively precise timing is required. It is highly stable even when exposed to various types of environmental conditions. It is also suitable for vibration-sensitive applications since it uses a thick-film structure on an alumina substrate for improved vibration resistance. Additionally, SITs are usually used in audio and video applications, testing and measurement equipment, clock generators, and medical devices, among many other applications.

The working principle of SITs relies on two main components, namely the oscillator and the frequency-adjusting circuit. The oscillator of SITs consists of a carbon resistor and a quartz material with electrodes connected at both ends. The quartz material acts as a negative temperature coefficient, meaning that its frequency will decrease as the temperature increases. This characteristic of quartz avoids uncontrollable frequency drift of the oscillator, thus making accurately controlled performance possible.

The frequency-adjusting circuit in an SIT oscillator adjusts the frequency of the oscillator by changing the current. It is usually composed of a fixed resistor, a voltage-controlled variable resistor, and a capacitor. This circuit works by gradually increasing the voltage at the variable resistor, while at the same time discharging the capacitor. This creates an AUTO control of the frequency, which enables the oscillator to reach a steady frequency of the quartz material. This frequency is usually within a few ppm (parts per million) of the nominal frequency, which means relatively precise timing can be achieved.

In summary, SIT1602BC-82-28N-12.000000T (SIT) is a type of oscillator that finds its use in many industrial applications where precise timing is required. It consists of an oscillator and frequency-adjusting circuit that works together to provide precisely controlled performance, making it suitable for vibration-sensitive applications. With its stable characteristics and AUTO control of frequency, SIT oscillators are highly reliable and widely used in audio and video applications, testing and measurement equipment, clock generators, and medical devices, among many others.
