While in medical devices, it is used as the timing basis for high accuracy measuring and monitoring systems.

Working Principle of SIT9120AI-2BF-33E125.000000Y oscillator

The working principle of SIT9120AI-2BF-33E125.000000Y oscillator is based on the “negative resistance” property of a circuit known as the Colpitts oscillator. It consists of several components, including a Darlington transistor, two capacitors and one or two inductors. The circuit works by providing Negative Feedback to operate in a Loop. When the voltage gets too high, the transistor conducts to provide a negative resistance. This forces the current in the circuit to flow backwards, so that the stored energy in the circuit is released to reduce the voltage. Meanwhile the current flow through the inductor reverses direction, resulting in a decrease in the inductance. This, in turn, causes a decrease in the current, reducing the voltage even more, until it reaches the threshold set by the usable capacitors. The decreasing process then repeats, resulting in a periodic oscillation.

In conclusion, SIT9120AI-2BF-33E125.000000Y is an oscillator that is widely used in many applications due its RF signal output and wide voltage range. Its working principle is based on negative resistance phenomenon and the Colpitts Oscillator circuit.
