Its a 10 MHz SMD Crystal Oscillator HC49/US Package. The crystal oscillator is used in microprocessor clock, network card, various consumer electronics, etc. It operates on the principle of inverse piezoelectric effect in which an alternating voltage applied across the crystal surfaces causes it to vibrate at its natural frequency. It is these vibrations which eventually get converted into oscillations, The crystal oscillator is used in microprocessor clock, network card, various consumer electronics, etc.

Features:

• Its Frequency range is 10 MHz 
• Its package is HC49/US
• Its color is silver
