Crystals are a fundamental part of many types of electronics, from tiny quartz-based watches to transistors and larger semiconductor chips. As such, they are used in a variety of applications, from pulse-shaping oscillators to radio-frequency oscillators. One example of a crystal is the CA-301 49.3800M-K (PB FREE), which is a crystal oscillator made with a crystal, a capacitor, and an amplifier. The crystal of the CA-301 contains a cut quartz crystal, a pair of contacts and a base material. The crystal generates an electrical signal at a frequency determined by its cut, when its contacts are excited by an externally-applied voltage. The frequency of oscillation is determined by the dimensions of the quartz crystal and its physical characteristics.

The CA-301 49.3800M-K (PB FREE) crystal has an application field that is designed for the electricity meters, signal lights, medical instruments, electric toy and educational instrument. Also, this crystal is used in LCD panels and mobile phones. These crystals are low power, with low-jitter, and high-stability features, making them ideal for many applications. For example, it is used to generate a frequency signal for measuring and controlling radio frequency signals, pulse-shaping oscillators, and radio-frequency oscillators. It can also be used for temperature-compensated timing circuits in watches.

The working principle of the CA-301 49.3800M-K (PB FREE) crystal is based on the piezoelectric effect. When a voltage is applied to a quartz crystal, the crystal oscillates at its resonant frequency. This is because the quartz crystal is a piezoelectric material, meaning it is able to create an electric field when it is subject to mechanical stress. When a voltage is applied to the two contacts of the crystal, the crystal vibrates. The frequency of the vibrations is determined by the characteristics of the crystal.

The crystal of the CA-301 49.3800M-K (PB FREE) oscillator is coupled with a matched capacitor and a feedback amplifier that are responsible for the oscillation of this crystal. The transistor at the center of the oscillator acts as an amplifier to maintain the resonance of the oscillator, which is determined by the frequency of the crystal. The capacitor is what determines the frequency of the oscillation. When the frequency of the crystal changes, the capacitor compensates and keeps the oscillator frequency stable.

The CA-301 49.3800M-K (PB FREE) crystal is a valuable electronic device for many types of applications. It is a reliable and low-jitter source of a stable frequency signal, and can be used in a variety of applications from clocks and alarms to medical instruments and electricity meters. It is a reliable, low-power, low-jitter, and high-stability crystal.
