8J-27.120METV-T

Crystals Overview

The TXC Corporation 8J-27.120METV-T is a MHz quartz crystal resonator designed for surface-mount applications. It operates at a fundamental frequency of 27.120 MHz with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 100 ohms. The component features a compact 1.2 mm x 1.05 mm seam seal package with four ceramic pads. Frequency tolerance and stability are rated at ±10 ppm at 25°C and ±10 ppm across the -30°C to +85°C operating temperature range.

Crystals Feature Summary

• Utilizes a seam seal construction with a ceramic base for enhanced mechanical robustness.
• Supports surface-mount technology via a four-pad configuration for automated assembly.
• Maintains strict frequency stability within a wide industrial temperature range.

Crystals Applications

• High-frequency clock signal generation in digital circuits
• Timing references for microcontroller systems
• Communication interface synchronization modules

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the seam seal package dimensions align with the target PCB footprint requirements. Cross-reference the ESR value with oscillator circuit design constraints to guarantee reliable startup performance under varying load conditions.

Crystals Selection Notes

Select this component when a small form factor is critical for high-density board layouts. The 8 pF load capacitance requires matching external circuit capacitors to achieve the specified frequency accuracy. Ensure the application environment remains within the -30°C to +85°C range to maintain the guaranteed ±10 ppm stability without derating.

Crystals Part Context

This part belongs to the TXC 8J series, which specializes in miniature quartz crystals for space-constrained electronics. The series utilizes advanced seam sealing techniques to protect the quartz element from environmental stressors while maintaining low profile characteristics suitable for modern consumer and industrial devices.

Crystals Replacement Considerations

Direct substitutes must match the 27.120 MHz frequency, 8 pF load capacitance, and 1.2x1.0 mm package dimensions. Verify that alternative components offer identical ±10 ppm stability across the same temperature range and compatible ESR values for circuit interchangeability.
