Crystals are solid materials having an orderly, repetitive arrangement of atoms or molecules. Their atomic or molecular structure makes crystals naturally suited for many types of applications, including the FA-238 27.0000MD50Y-AC.

This type of crystal uses a quartz blank cut and then lapped to form a plate-like resonator. The thickness of the blank is carefully controlled and the face is polished perfectly flat and parallel with the other sides of the blank. This is then mounted on a base plate, and the air between the plate and the substrate is replaced with a special material known as a dielectric filler. The choice of material is carefully matched to the frequency at which the crystal should oscillate. Once this is done, the frequency of the oscillator is adjusted precisely by trimming the blank.

The FA-238 27.0000MD50Y-AC crystal is a miniature flat quartz crystal, mounted and tailored for a frequency range from 27MHz to 50MHz. It features low profile, low dissipation factor, and wide temperature operating range. Its standard temperature range is from -20 to +75 °C, and its frequency stability is up to +-30 ppm.

The crystal is typically used in wireless communication for radio frequency (RF) oscillators and radio receivers, as well as automotive, communication and aviation applications, including in mobile phones, Wi-Fi, navigation, and time keeping. In addition, it is suited to alarm systems, data logging, pulse generation, and frequency counters. The crystal is also suitable for use in GPS systems, and can be utilized in a range of systems, including autopilot, precision navigation, and location tracking.

The working principle of the FA-238 27.0000MD50Y-AC crystal is based on the vibration of the quartz crystal when an electric current is applied to it. The crystal vibrates at a stable, accurate frequency. The current is then fed into a tuned tank circuit consisting of a capacitor and an inductor. The discrete operating values of the capacitor and inductor are carefully calculated to match the frequency of the quartz crystal.

This type of crystal oscillator is popular due to its low power consumption, small size, high precision, and excellent frequency stability. The ability to make precise frequency adjustments is vital for communications, navigation, electronics and radio communication applications that require signal stability, accuracy, and reliability.

In conclusion, the FA-238 27.0000MD50Y-AC crystal has many applications, including in wireless communication and radio receivers, automotive, communication and aviation systems, GPS, autopilot, and precision navigation. The crystal is based on the vibration of the quartz crystal when an electric current is applied to it, and its operation is based on a tuned tank circuit consisting of a capacitor and an inductor. The crystal is known for its low power consumption, small size, high precision, and excellent frequency stability.
