The 7I20000F12UCG SMD Crystal Resonator is an SMD-5032_4P item manufactured by SJK, and compliant with the Restriction of Hazardous Substances Directive (RoHS). It is an electronic part used to generate a frequency stable oscillation signal in electronic circuits, such as microprocessors, radios and clock oscillators. It is a four-pin SMD (Surface Mount Device) component with a ceramic package and a center-tapped resonance structure. It operates at a resonant frequency of 12MHz, making it ideal for CPUs and digital-signal processors (DSPs). This component is suitable for both automated equipment and manual processing. It has a high precision and frequency stability of at least ±100ppm as well as a low minimum vibration level of 30.0dB over a temperature range of -55°C to 125°C.
