The 49SAC11059202060 DIP Crystal Resonator is an electronic component from JGHC that consists of a quartz crystal and two electrodes sealed in a ceramic package. It is designed to oscillate at a specific frequency and provide an accurate clock signal used in communications systems, radio transmitters, and as a timing reference for oscilloscope triggers. The HC-49S RoHS version of the resonator meets European Union's Restriction of Hazardous Substances (RoHS) compliance for lead-free components. It is a two-lead device with a 9.68 mm width, 4.0 mm length, and height of just 1.6 mm, allowing for a compact PCB footprint. The resonator has a calculated frequency of 20.00 MHz and boasts a maximum frequency stability of 40 ppm. It operates in temperatures ranging from -20 to 70 °C.
