Crystals

Crystals are naturally occurring solids formed from the regular lattice arrangement of atoms or molecules. This repetition in structure gives crystals their remarkable properties such as their optical, electrical and mechanical characteristics. Crystals have been used for centuries in a variety of industrial, medical and technological applications.

402F204XXCJT Application Field and Working Principle

The 402F204XXCJT is a type of crystal used for precision timing and oscillator circuits. It is a SMD type crystal and is typically soldered onto the PCB of a circuit where precise timing is needed. The 402F204XXCJT has a specified frequency range from 8.192 to 25.000 MHz. The crystal is made from a quartz crystal blank with electrodes at the end of the blank in order to drive current through the quartz crystal. When current is applied to the crystal, the expanding and contracting of the crystal causes the quartz to vibrate at the fundamental frequency. This frequency is then “tuned” by adding two series capacitors to the circuit. By varying the capacitance, the desired frequency of oscillation can be achieved.

The 402F204XXCJT crystal is used in applications where extremely precise timing is needed. These applications can range from communication systems, such as cellular phones, to microcontroller and memory circuits. In addition, the 402F204XXCJT can be used in precision clocks or other circuits where precise timing is necessary.

In conclusion, the 402F204XXCJT crystal is an excellent choice for precision timing and oscillator circuits. Its built-in series capacitors allow for precise tuning of the crystal to the frequency desired by the user. It is an excellent choice for a variety of industrial, medical and technological applications.
