Crystal Oscillator 4MHz 20pF HC-49S
The Crystal Oscillator 4MHz 20pF HC-49S is a fundamental passive electronic component designed to generate a highly stable and precise clock signal at a frequency of 4.000 MHz. This component utilizes the piezoelectric effect in a precisely cut quartz crystal to provide the necessary frequency reference for microcontrollers, digital signal processors, and other timing-sensitive electronic devices. The crystal is housed in the widely used, hermetically sealed, low-profile HC-49S package, which is well-suited for through-hole mounting on printed circuit boards (PCBs) and is designed for applications where space conservation is a priority.
Features:
- Precise fundamental frequency output of 4.000 MHz.
- Low-profile HC-49S case style for compact circuit designs.
- Specified 20pF load capacitance for optimal integration with common oscillator circuits.
- Tight Frequency Tolerance of 30 ppm for high-accuracy timing.
