Description

The 4 MHz SMD Crystal Oscillator in an HC49/US package is a surface-mount quartz crystal oscillator that offers a precise and stable 4 MHz frequency. It is widely used in clock generation and timing applications in embedded systems, microcontrollers, communication devices, and other digital circuits. The compact HC49/US package provides space efficiency, making it ideal for high-density PCB layouts.

Features

  • Accurate 4 MHz Frequency Output: Ensures reliable and consistent clock signals for various timing applications.
  • Compact HC49/US Package: Low-profile, surface-mount package suitable for space-constrained designs.
  • Low Power Consumption: Efficient for use in battery-powered or energy-sensitive devices.
  • Long-Term Frequency Stability: Minimal frequency drift over time due to aging or environmental changes.
  • Wide Operating Temperature Range: Suitable for both standard consumer and industrial environments.
