Crystals

Crystals are a component of electrical products, and they are used to provide precision timing and clock signals. The CPFBZ-A2C4-32.768KD12.5 crystal is an example of a type of crystal used for this purpose. The crystal has a frequency of 32.768 kHz, and it is rated for a maximum operating temperature of 125° Celsius.

Application Field

The CPFBZ-A2C4-32.768KD12.5 crystal is an ideal component for applications such as real-time clock (RTC) modules, mobile phones, portable electronics, and industrial control systems. It is used for timing and clocking functions, as well as other related tasks, such as motor speed controllers and sensor stimulation.

Working Principle

The operating principle of the CPFBZ-A2C4-32.768KD12.5 crystal involves generating a precise frequency that is derived from its vibrational characteristics. This frequency is determined by the size and shape of the crystal, and it is typically referred to as the "load capacitance".When the crystal is powered up, a current is driven through its terminals, which causes its amplifying piezoelectric layers to vibrate in its crystalline form. These vibrations create the needed frequency, which is provided to the underlying circuit. As the frequency is maintained, it allows the circuit to perform tasks at a precise rate.

Other Considerations

In addition to the operating frequency, there are other important characteristics of a crystal that need to be taken into consideration. These include factors such as the temperature coefficient, the aging rate, and the equivalent series resistance (ESR).The temperature coefficient gives an indication of how the frequency of the crystal changes as the temperature fluctuates, while the aging rate gives an indication of how the frequency changes over time. The ESR of the crystal is the measure of the energy loss when current is supplied to the crystal. This is important, as it must be kept within an acceptable range to ensure proper functioning.It is also important to note that crystals are more prone to shock and vibration than other components, and as such, they must be handled carefully. This is especially true when they are being assembled and soldered onto a board. In these cases, it is important to use appropriate protective measures to prevent any damage to the crystal.In conclusion, the CPFBZ-A2C4-32.768KD12.5 crystal is a useful component for applications where precision clocking and timing functions are required. It is relatively durable, but it must still be handled carefully to ensure its proper functioning. Additionally, factors such as the temperature coefficient and ESR must be taken into consideration for proper operation and reliability.
