The 402F204XXCKT type crystals are semi-precision crystals manufactured by Vishay, and are applied in a wide range of consumer electronic devices, such as remote controllers, PC motherboards and chip configurations. This article will discuss the application fields and the working principle of 402F204XXCKT crystals.

Application Fields

402F204XXCKT crystals are usually used in consumer electronics ranging from remote controls to computers, as well as various other common consumer appliances. The wide range of applications of 402F204XXCKT crystals makes them especially suitable for consumer electronics, as they are able to work with a wide variety of different kinds of circuits. For example, 402F204XXCKT crystals can be used in television remote controls, which often require time base accuracy in order to function properly. The crystals’ precision allows for the television’s remote control to accurately and reliably respond to signals sent by the user. In addition, 402F204XXCKT crystals are often used in PC motherboards, as they are able to help maintain a reliable frequency required for certain operations. The crystals also help to ensure stable data transmission and reception, as they are able to detect signals sent by the computer and respond accurately based on the crystal’s frequency. 402F204XXCKT crystals are also used in chip configurations, as they are able to provide accurate signals required for certain operations to be performed. This helps ensure that signals sent by the chip are accurate, ensuring that the chip performs its intended operations properly.

Working Principle

Crystals such as the 402F204XXCKT are used to provide a frequency or time-based signal to other circuits in order to maintain accuracy. The crystal works by using an oscillator to generate a continuous, periodic signal at a specific frequency determined by the crystal itself. The 402F204XXCKT crystal is actually composed of two plates (the quartz plate) and the electrodes that are located on the crystals’ outermost layer. The quartz plate is made of quartz, a naturally occurring material with piezoelectric properties. Meaning that when the quartz plate is made to vibrate, it will generate an electrical charge. The electrodes that are located on the outside of the crystal act as alternating current switches, meaning they can be used to manipulate the electrical charge that is generated by the quartz plate. By doing this, they can convert it into a signal with a specific frequency or time base, which can then be used by other circuits. In conclusion, the 402F204XXCKT crystals are semi-precision crystals manufactured by Vishay that are often used in consumer electronic devices. The wide range of applications of 402F204XXCKT crystals make them especially suitable for consumer electronics, as they are able to work with a wide variety of different applications and provide accurate signals for operations. The crystals work by using an oscillator to generate a signal of a specific frequency, using the quartz plate and the electrodes located on the crystal’s exterior.
