The 5S0-1000A2020-00 is a DIP Crystal Resonator manufactured by XTY with 49S shape and RoHS compliance. It is an electronic part that is designed to create an electrical signal at a specific frequency and prdouce precise timing or control signals required by various types of electronic devices, such as microcontrollers, oscillators, phase-locked loops, and radio frequency (RF) circuits. It is usually packaged in a dual-in-line package (DIP), which is a small plastic package with two sets of pins (long and short) arranged in a row that can be soldered to a printed circuit board (PCB). This component is usually used in oscillators, timers, and car audio systems.
