It comes in a miniature 3.2 x 2.5mm size, with a frequency tolerance of +25/-20ppm at 25 °C and +0/-50ppm at -10 - +60 °C. It has a maximum voltage of 10Vrms, a load capacitance of 12.5 pF, a series resistance of 25 ohms, a driving level of 10 uW and a total aging of 0.2ppm/yr max.

Application Field of CA-301 50.4533M-K: PB FREE

The CA-301 50.4533M-K: PB FREE crystal is used in a variety of applications, such as switching power supplies, baseband modems, transceivers and audio ICs. It is particularly useful for applications where low power consumption is a priority. It is also well-suited for consumer electronics and digital mobile products, due to its tiny size and low cost.

Additionally, the PB FREE crystal can be used in medical appliances where electromagnetic interference (EMI) suppression is critical. The PB FREE crystal is also suitable for military applications, as it has superb temperature characteristics and can be powered with a low voltage.

Working Principle of CA-301 50.4533M-K: PB FREE

The CA-301 50.4533M-K: PB FREE crystal works by converting mechanical energy (in the form of physical vibrations) into electrical energy. This is done through the use of the piezoelectric effect, which states that mechanical vibration can generate a voltage. When the electrodes of a piezoelectric material are exposed to mechanical pressure, an electrical charge is generated and a current is induced in the attached circuit.

The physical vibrations of a crystal resonator occur at a specific frequency and can be used to create a signal of a precise frequency. When an alternating current is applied to the crystal resonator, it will vibrate at its natural frequency, producing an alternating current signal of the same frequency. This makes the crystal a very useful component for generating a frequency signal for oscillators and timing circuits.

The CA-301 50.4533M-K: PB FREE crystal is one of the best crystal resonators available on the market, and its size, frequency tolerance and power requirements make it an ideal choice for many applications.

Conclusion

The CA-301 50.4533M-K: PB FREE is a crystal resonator manufactured by TDK Corporation. It is most suitable for applications that require low frequency tolerance and power consumption, such as switching power supplies, baseband modems and transceivers, as well as medical and military applications. The working principle behind the CA-301 50.4533M-K: PB FREE is based on the piezoelectric effect, where mechanical vibrations are converted into electrical energy and then into a frequency signal for oscillators and timing circuits. With all of this in mind, the CA-301 50.4533M-K: PB FREE is an excellent choice for anyone looking for a reliable, high-quality crystal resonator.
