Crystals, such as the model of FC5BQCCMC18.432-T1, are used in various applications and industries. They are mainly used as frequency referenece sources in oscillators, timers and frequency synthesizers. They offer stable, accurate and repeatable results in a range of frequencies. In this article, we will discuss the application fields of FC5BQCCMC18.432-T1, as well as its working principle.

The FC5BQCCMC18.432-T1 crystal comes as an ultra-compact, surface-mount package. It is designed to be used in demanding sensor applications, especially in the automotive and avionics industry. Its small size, low power consumption and extended temperature range make the model suitable for tight, high-performance and energy-efficient designs. It can also be employed in other embedded applications, such as medical equipment and consumer electronics. In order to meet different needs, the FC5BQCCMC18.432-T1 crystal supports multiple working frequencies, including 18.432 MHz and 20.46 MHz.

The working principle of FC5BQCCMC18.432-T1 can be divided into three steps: excitation, oscillation and frequency control. In the excitation step, an electrical impulse is applied to the crystal across the electrodes. This impulse induces a small physical displacement in the crystal, resulting in the formation of a ‘mechanical resonance’. This resonance then causes the crystal to vibrate at its own natural frequency.

In the oscillation step, the oscillated frequency is controlled by the crystal’s thickness, size and shape. The mass of the crystal is also important, as this determines the frequency at which it can oscillate. The oscillator then receives input from the crystal and amplifies it to generate the desired frequency.

Finally, in frequency control step, the output of the oscillator is used to regulate the crystal oscillation. This happens in two ways; firstly by changing the frequency of the electric pulses sent to the crystal (known as “frequency pull-in”), and secondly by controlling the feedback circuit of the oscillator (known as “amplitude pull-in”).

The FC5BQCCMC18.432-T1 crystal is well-suited for precision time-keeping and frequency controlling applications. With its high accuracy, low power consumption and extended temperature ranges, it is ideal for small, power-efficient designs.
