CSTCR6M60G55Z-R0

Resonators Overview

The Murata Electronics CSTCR6M60G55Z-R0 is a surface-mount ceramic resonator operating at a nominal frequency of 6.6 MHz. It features an integrated load capacitance of 39 pF, eliminating the need for external capacitors in oscillation circuits. The component offers a frequency tolerance of ±0.5% and an equivalent series resistance (ESR) of 50 Ohms. Designed for robust performance, it operates within a temperature range of -40°C to +125°C. The physical dimensions are 4.5 mm in length, 2 mm in width, and 1.2 mm in height, utilizing SMD/SMT termination style.

Resonators Feature Summary

• Integrated internal load capacitor design removes requirement for external components
• Compact surface-mount package suitable for high-density PCB layouts
• Wide operational temperature range ensures reliability in harsh environments

Resonators Applications

• Microcontroller clock signal generation
• Real-time clock circuits
• Communication module timing references

Resonators Procurement Notes

Verify the specific suffix Z-R0 against the official Murata datasheet to confirm packaging and tape-and-reel specifications. Ensure the target circuit design accounts for the built-in 39 pF load capacitance to prevent frequency deviation. Cross-reference the ESR value with the oscillator driver strength requirements to guarantee stable startup conditions.

Resonators Selection Notes

Select this component when a precise 6.6 MHz reference is required without external tuning capacitors. Consider the ±0.5% tolerance for applications demanding tight frequency accuracy. Evaluate the 50 Ohm ESR against the microcontroller's oscillator input impedance to ensure proper drive level and avoid overdriving the crystal port.

Resonators Part Context

This part belongs to the CERALOCK CSTCR_G series, which specializes in small-capacity chip-type ceramic resonators. The series is engineered to replace traditional quartz crystals in cost-sensitive applications where slight frequency stability trade-offs are acceptable. The G55Z designation indicates specific electrical characteristics and packaging configurations within the broader Murata resonator portfolio.

Resonators Replacement Considerations

Direct substitutes include CSTCR6M00G55Z-R0 for 6 MHz or CSTCR6M60G53Z-R0 for alternative tolerance levels. Verify that any replacement maintains the same 39 pF internal capacitance and 50 Ohm ESR to preserve circuit stability.
