7M-20.000MEIQ-T

Crystals Overview

The 7M-20.000MEIQ-T is a seam seal quartz crystal manufactured by TXC Corporation, designed for surface mount applications in the 3.2x2.5 mm package. It operates at a fundamental frequency of 20 MHz with a load capacitance of 10 pF and an equivalent series resistance of 50 Ohms. The component features high frequency stability, specified at ±10 ppm relative to 25°C and ±20 ppm over the extended temperature range of -40°C to +85°C. This device utilizes a four-pad no-lead SMD configuration suitable for automated assembly processes.

Crystals Feature Summary

• Seam sealed construction for enhanced environmental protection
• High frequency stability within tight tolerance limits
• Surface mount design optimized for automated placement

Crystals Applications

• Precision timing circuits requiring stable clock references
• Consumer electronics with space-constrained layouts
• Industrial control systems operating in variable temperatures

Crystals Procurement Notes

Verify the specific suffix IQ against official TXC documentation to confirm the exact stability grade and temperature range specifications. Ensure compatibility with standard reflow soldering profiles for 3.2x2.5 mm seam seal packages. Confirm that the 10 pF load capacitance matches the oscillator circuit requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a compact 3.2x2.5 mm footprint is required alongside strict frequency stability needs. The ±10 ppm initial accuracy makes it suitable for applications where precise timing is critical without the need for external calibration. Consider the 50 Ohm ESR when designing the drive level constraints for the host oscillator circuit.

Crystals Part Context

This part belongs to the broader category of MHz quartz crystals from TXC Corporation. It represents a standard solution for general-purpose timing applications where size reduction is prioritized. The seam seal technology distinguishes it from ceramic resonators, offering superior long-term stability and aging characteristics for reliable electronic system operation.
