CSTCC3M20G56-R0

Resonators Overview

The CSTCC3M20G56-R0 is a surface-mount piezoelectric ceramic resonator from Murata Electronics, part of the CERALOCK series. It operates at a nominal frequency of 3.2 MHz with a tolerance of ±0.5%. The component features an integrated load capacitance of 47 pF and a maximum impedance of 80 Ohms. Designed for SMD/SMT assembly, it measures 7.2 mm in length, 3 mm in width, and 2.1 mm in height. The device supports a standard operating temperature range from -20°C to +80°C.

Resonators Feature Summary

• Integrates internal load capacitors to simplify circuit design and reduce component count.
• Utilizes piezoelectric ceramic technology for stable frequency generation.
• Offers high reliability through robust surface-mount construction.

Resonators Applications

• Microcontroller clock sources
• Digital signal processing circuits
• Communication interface timing

Resonators Procurement Notes

Verify current availability status as distribution channels may indicate limited stock or discontinuation. Confirm RoHS compliance details via official datasheets before integration. Ensure ordering suffixes match required packaging formats such as cut tape or reel specifications for automated assembly processes.

Resonators Selection Notes

Select this component when a compact, cost-effective clock source is required for low-frequency digital applications. The 47 pF internal capacitance matches common microcontroller requirements, eliminating external capacitor needs. Verify that the 3.2 MHz frequency aligns with system timing constraints and that the 80 Ohm impedance fits driver capabilities.

Resonators Part Context

This resonator belongs to the CSTCC_G series, characterized by larger physical dimensions compared to small-cap variants. It provides higher output amplitude due to its larger electrode area. The CERALOCK branding indicates Murata's proprietary ceramic composition designed for consistent performance across industrial temperature ranges.

Resonators Replacement Considerations

Direct substitutes include other Murata CERALOCK models with identical 3.2 MHz frequency and 47 pF load capacitance. Cross-reference pin-out compatibility and mechanical footprint dimensions when evaluating alternative suppliers or updated product revisions within the same family.
