Crystal Oscillator 4.000MHz 49S 20PPM 20pF 40Ω

From the shop's description

Crystal Oscillator 4.000MHz 49S 20PPM 20pF 40Ω The Crystal 4.000MHz 49S 20PPM 20pF 40Ω is a passive quartz crystal resonator that generates a highly stable 4.000MHz reference frequency when used with an oscillator circuit. It is widely used in microcontrollers, communication equipment, industrial controllers, and digital logic systems where precise timing and synchronization are essential. With a frequency tolerance of ±20ppm, it provides reliable clock accuracy for demanding electronic applications. Housed in the industry-standard HC-49S through-hole package, this crystal features a 20pF load capacitance and a low 40Ω equivalent series resistance (ESR) for stable oscillator start-up and efficient operation. Its compact metal package offers excellent long-term reliability and is suitable for both prototyping and production designs. Features: Stable 4.000MHz frequency reference.
