Q22FA2380004700 crystal oscillator suitable for convenient electronic instrument applications FA-238 passive crystal oscillator

    With the progress of the network era, the development of Bluetooth communication, wearable, mobile Internet and other technologies, as well as digital electronic products such as portable devices, crystal oscillators are indispensable components and play a very important role. Convenient electronic instruments, especially during the epidemic, have become essential tools for measuring body temperature with the most commonly used forehead temperature gun (infrared thermometer). It can accurately measure temperature in 1 second without laser points, eliminating potential harm to the eyes, avoiding contact with human skin, and avoiding cross infection.

    The infrared thermometer is designed for measuring human frontal temperature as a benchmark, achieving non-contact temperature measurement with simple and convenient operation. One second can accurately measure temperature, effectively reducing the risk of cross infection between people. The function of a crystal oscillator is to provide a reference clock signal for the MCU to ensure the smooth progress and completion of various instructions. If the crystal oscillator is unstable during actual operation, such as excessive frequency deviation or failure to vibrate, it will directly cause the MCU to lose its command function. The adverse phenomena include not turning on, the LCD display screen cannot light up, or temperature measurement delay. The infrared thermometer is a portable electronic instrument that requires battery power, so there is a low power demand for crystal oscillators. The selection of crystal oscillators is mostly chip mounted, small in size, and low in power consumption. In short, the more stable and accurate the crystal oscillator works, the faster and more accurate the temperature measurement response of the infrared thermometer gun.

    The Epson Q22FA2380004700 crystal oscillator (FA-238 passive crystal oscillator) has become an ideal choice for convenient electronic instruments, especially infrared thermometers, due to its high precision, low power consumption, miniaturization, high reliability, and wide temperature range. It not only improves the accuracy and stability of temperature measurement, but also extends the battery life of the equipment, adapts to various usage environments, and meets the high requirements of modern users for convenient electronic instruments.The Epson crystal oscillator FA-238 is a small volume 3.2x2.5mm passive crystal oscillator, quartz crystal resonator, four pin SMT crystal oscillator, with a frequency range of 16MHz to 60MHz and operating temperatures of -40 ℃ to+85 ℃ (+105 ℃). It has the characteristics of ultra small size, lightweight, heat resistance, and environmental resistance.
