Crystals, also known as frequency control elements, are mainly used as frequency source components in various electronic systems, such as oscillator circuit, embedded processor, and various communication circuits. There are various types of crystals based on the types of materials used and the frequency of operation, and one example is CA-301 50.4667M-K.

CA-301 50.4667M-K, or otherwise known as PB-freeCrystal, is a wide-range frequency crystal element, used in multiple electronic products. With superior stability, low deviation, and low noise characteristics, the technology is particularly suitable for medium and high-end products with audio or video applications, or communication devices and high-frequency oscillators. As for packaging, this PB-free crystal is provided in a standard 9.8mm x 2.5mm SMD package, which offers a relatively higher packing density than regular crystals.

The characteristic frequency of these type of crystals is determined by the size, shape and material of the oscillator and various parameters. When it comes to working principle, the internal structure of a PB-free crystal oscillator consists of a quartz crystal cut into a specific shape. The quartz crystal is formed of two separate pieces, called an atteunuator and a resonator. When an alternating current flows through the crystal, this causes the quartz crystal to vibrate and produce an electrical signal.

As the current supplying the crystal continues to change, this will cause the frequency to change as well. Depending on the frequency of the current, the quartz crystal will vibrate and produce an alternating current at a specific frequency. The frequency of this current is determined by the size and shape of the quartz crystal. This frequency is referred to as the resonance frequency, and can be adjusted by carefully selecting the size and shape of the quartz crystal.

This resonance frequency can also be further adjusted by applying an external voltage or a mechanical stress to the crystal, or by surrounding the crystal with a material that has an acoustic impedance different from that of the quartz crystal. By changing these factors, it is possible to fine-tune the crystal to achieve accuracy within the desired range.

In addition to its superior stability, accuracy, and lack of noise characteristics, the CA-301 50.4667M-K is also a very cost-effective solution. Since the crystal is pre-assembled and the frequency adjustment is easy to adjust, using this crystal is more economical than using discrete components, and allows for greater flexibility in terms of design.

Overall, the CA-301 50.4667M-K PB-free crystal element has excellent characteristics that make it suitable for various applications, offering superior stability, accuracy, and low noise, as well as a cost-efficient solution. With its wide range of frequency and simple packaging, this type of PB-free crystal is a great choice for many electronic products such as oscillator circuits, embedded processors, and communication systems.
