Details
The Murata CSTCE20M0V53-R0 is a ceramic resonator from the CERALOCK® series designed for frequency control and timing applications. It features a built-in 15pF capacitor, eliminating the need for external load capacitors in many applications. This SMD component is ideal for microcontroller clock circuits and timing applications requiring 20MHz operation.
Description
The CSTCE ceramic resonator is a piezoelectric ceramic device that vibrates at a specific frequency when excited. The built-in capacitor provides the necessary load capacitance for stable oscillation. These resonators are commonly used as clock sources for microcontrollers, microprocessors, and other digital circuits where precise timing is required. The CSTCE series is designed for higher frequency applications compared to the CSTCR series.
