Crystals, in the context of electronic components, refer to piezoelectric crystals which are primarily used as frequency control devices. These components function by oscillating at specific frequencies when voltage is applied to them, which is crucial for maintaining the timing accuracy in electronic devices. Commonly made from quartz, these crystals are essential for providing stable and precise frequencies that ensure the smooth operation of consumer electronics, telecommunications, and computers. Their ability to generate consistent oscillations makes them indispensable in applications such as clocks, radios, and processors where timing is critical.
Specific applications of crystals include their use in watches for precise time-keeping, in communication equipment like radios and cellphones to maintain clear signal transmission, and in computer motherboards to regulate the timing of CPU operations. The main characteristics of these crystals include high stability, low power consumption, and excellent frequency precision which make them highly sought after in any application requiring accurate timing and synchronization. Prominent manufacturers of these crystals include companies like Epson, NDK, and Kyocera, who are recognized for their quality and reliability in the production of piezoelectric crystals.
