Crystals

Crystals are the most popular and widely used components in modern electronics applications. Crystals play a vital role in essential electronics components such as frequency controllers, resonators, oscillators, and transducers. The use of crystals in modern electronics applications is rapidly increasing due to their unique physical properties and ability to accurately convert electrical signals into frequency signals.

402F4801XIDR application field and working principle

The 402F4801XIDR is a 10 mm SMD crystal designed for use in miniaturized electronic devices. It has a frequency of 12.8 MHz and a maximum drive level of 100 µW. The crystal is designed for use in wireless communication, automotive electronics, radio frequency (RF) applications, digital read-out devices, and other miniaturized electronic devices.

The 402F4801XIDR is composed of a pair of electrodes placed on a quartz substrate. The two electrodes are connected to the two terminals of the crystal and act as the input and output points. The crystal contains a gap between the electrodes, which creates an inductive component. This component is called the L-C element, and this is where the resonance of the crystal is created.

When an AC voltage is applied to the two terminals of the crystal, the L-C component of the crystal will oscillate at a specific frequency. This frequency is determined by the size of the gap and the amount of inductance in the component. The frequency of the crystal can be controlled by changing the gap size or the inductance of the component.

The 402F4801XIDR is designed to operate between 0.2V and 15V, making it suitable for operation in a wide variety of applications. The crystal can also be used in high-temperature applications without significant degradation in performance. The crystal is also temperature compensated, which helps to reduce temperature-related frequency shifts.

The 402F4801XIDR is an extremely versatile and accurate frequency controller, with a minimum operation frequency of 12.8 MHz. This makes the crystal suitable for use in a wide variety of applications including radio frequency applications, digital read-out devices, and automotive electronics.
