The ESB16.0000F12M25F with SMD Crystal Resonators 16MHz ±20ppm 49SMD RoHS is a small signal oscillator manufactured by MONEC. It has a frequency tolerance of ±20ppm, making it suitable for accurately controlling the oscillatory characteristics of a digital circuit. It offers an excellent frequency ageing and stability over temperature, and its low-profile surface mount design is well-suited for a variety of requirements. It features RoHS compliance, meaning it does not contain lead or heavy metal alloys, and meets the EU RoHS 2 Directive. The crystal resonators provide a low jitter oscillator that provides high frequency accuracy. It is suitable for use in oscillator circuits, radio frequency and transmission lines, signal generators, and other electronic equipment.
