CSTCE20M0V53A-R0

Overview

The Murata Electronics CSTCE20M0V53A-R0 is a ceramic resonator from the CERALOCK series, designed for surface-mount applications. It operates at a nominal frequency of 20 MHz with a load capacitance of 15 pF and a frequency tolerance of ±0.5%. The component features an SMD/SMT termination type within a compact package measuring 4.5 mm in length, 2 mm in width, and 1.6 mm in height. It supports a wide operating temperature range from -20°C to +80°C and is supplied in cut tape or reel formats.

Feature Summary

• Integrated small-capacitor design eliminates external capacitors
• High reliability through robust ceramic construction
• Compact surface-mount footprint for space-constrained layouts

Applications

• Microcontroller clock sources
• Communication interface timing circuits
• General-purpose oscillator circuits

Procurement Notes

Verify the specific suffix 'A' against the official Murata datasheet to confirm tolerance and packaging details. Ensure the ordering part number matches the required frequency stability and temperature range specifications. Cross-reference the manufacturer's latest documentation to validate RoHS compliance and REACH status before procurement.

Selection Notes

Select this component when a cost-effective alternative to quartz crystals is required for moderate precision applications. The integrated capacitor design simplifies PCB layout by reducing component count. Verify that the 20 MHz frequency aligns with the target system's clock requirements and that the ±0.5% tolerance meets the application's timing accuracy needs.

Part Context

This part belongs to Murata's CERALOCK family of ceramic resonators, which are widely used in consumer electronics and industrial equipment. The CSTCE series specifically targets applications requiring reliable frequency control without the complexity of external tuning components. It serves as a direct replacement for discrete crystal oscillator solutions in many standard digital circuits.

Replacement Considerations

Direct substitutes include other 20 MHz ceramic resonators with similar 15 pF load capacitance and ±0.5% tolerance. Verify package dimensions (4.5 x 2 x 1.6 mm) and operating temperature range (-20°C to +80°C) when evaluating alternatives. Ensure the replacement maintains the same SMD mounting style and electrical characteristics.
