8Q-27.120MEEV-T

Crystals Overview

The TXC Corporation 8Q-27.120MEEV-T is a seam seal quartz crystal resonator operating at a fundamental frequency of 27.12 MHz. It features a load capacitance of 8 pF and an equivalent series resistance (ESR) of 100 Ohms. The component offers a frequency tolerance of ±10 ppm at 25°C and stability of ±10 ppm over the operating temperature range of -20°C to +70°C. Housed in a compact 4-SMD, no-lead package with dimensions of 1.6 mm x 1.2 mm x 0.35 mm, it utilizes ceramic construction for reliable performance in surface-mount applications.

Crystals Feature Summary

• Seam seal construction ensures hermetic sealing for enhanced environmental protection and long-term reliability.
• Compact 4-SMD no-lead footprint facilitates automated surface-mount assembly and space-constrained designs.
• High frequency stability of ±10 ppm across the specified industrial temperature range supports precise timing requirements.

Crystals Applications

• Wireless communication modules requiring stable carrier frequencies
• Industrial control systems needing reliable clock sources
• Consumer electronics utilizing surface-mount technology

Crystals Procurement Notes

Verify the specific suffix 'E' against the manufacturer's current datasheet to confirm exact tolerance and stability specifications, as ordering codes may define critical electrical parameters. Ensure the selected variant matches the required load capacitance and ESR for the target oscillator circuit design to guarantee proper operation.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with tight ±10 ppm stability constraints. The 8 pF load capacitance must align with the host oscillator circuit's input capacitance. Consider the 100 Ohm ESR value for drive level compatibility and the -20°C to +70°C temperature range for environmental suitability.

Crystals Part Context

This part belongs to the 8Q series of seam seal crystals from TXC Corporation. The series offers various frequencies and tolerances in a standardized 1.6mm x 1.2mm SMD package. The 8Q designation indicates a specific ceramic seam seal construction distinct from other TXC crystal families like the 8J or 8K series.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz crystals with identical 8 pF load capacitance and ±10 ppm stability in a 4-SMD no-lead package. Verify pinout compatibility and ESR values when cross-referencing with components from other manufacturers to ensure circuit performance parity.
