Crystals serve as foundational components of many electronic devices and circuitry. CA-301 50.3967M-K is a type of crystal and a frequency-determining component used for electronic timing and control such as for frequency control in the example oscillator circuits. In particular, CA-301 50.3967M-K is a Hand-Held Size, RoHS compliant china PB FREE crystal, allowing it to be used in various fields according to its application field and working principle.

PB FREE Application Field

CA-301 50.3967M-K’s application field is mainly in the communication field, particularly in point-to-point radios and the gigi Ethernet. This crystal component is also suitable for applications in TV tuners, VoIP, and sound cards, among others. Its capabilities allow it to resonate using an incoming radio frequency and generate an auxiliary radio frequency signal called an IF signal.

The design of the component, coupled with its PB free disposition, also allows it to operate as a digital filter in filtering out undesirable frequencies from digital signals and enable the transmission of clean, filtered digital signals with lower levels of noise present. CA-301 50.3967M-K’s application field also spans in power electronics including AC/DC converters and in renewable energy harvesting, as it is compatible with generators and active rectifiers.

Working Principle

In general, crystals are made of quartz and materials with a crystalline structure, and work based on what is known as the piezoelectric effect. This effect occurs when a material is deformed, such as when force is applied to it, and the application of an electric field will cause the material to deform and produce an oscillating electric current. Similarly, the application of an external voltage will cause a crystal to oscillate. As such, CA-301 50.3967M-K works on this basic principle, but with a few variations. Firstly, it uses a cut of quartz with a slightly different angle, which changes the vibration and noise frequency.

The quartz inside the component is itself enclosed in two metal cans, which feature a metal plate on the outside. This plate serves to amplify the crystal’s vibration, allowing it to generate a much higher and cleaner frequency. Additionally, the metal can is also designed to contain and dissipate heat, allowing the component to remain functional even when running at full power. The plate also helps to reduce surface noise and press noise.

Conclusion

The CA-301 50.3967M-K is a PB FREE Hand-Held Size RoHS compliant China crystal designed for a wide variety of applications. It works on the same basic principle as traditional crystals, but is equipped with additional features for improved heat dissipation, noise filtering, and frequency output. This makes it suitable for communications, sound cards, and AC/DC converters, and beyond.
