7M-20.000MEIE-T

Crystals Overview

The 7M-20.000MEIE-T is a surface-mount MHz quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 20.000 MHz with a load capacitance of 12 pF and an equivalent series resistance of 50 Ohms. The component features tight frequency stability of ±10 ppm at 25°C and ±20 ppm across the -40°C to +85°C temperature range. It utilizes a 4-SMD, no lead package with dimensions of 3.2 mm x 2.5 mm, employing a seam seal construction for enhanced reliability.

Crystals Feature Summary

• Seam seal construction for robust environmental protection
• High frequency stability suitable for precision timing
• Surface mount design for automated assembly

Crystals Applications

• Precision clock generation in consumer electronics
• Timing references in automotive infotainment systems
• Synchronization circuits in industrial control modules

Crystals Procurement Notes

Verify the specific suffix MEIE-T against official datasheets to confirm the ±10 ppm stability and seam seal construction. Ensure the 12 pF load capacitance matches the target circuit requirements. Confirm RoHS compliance status prior to integration. Cross-reference the 4-SMD footprint dimensions with PCB layout specifications to guarantee mechanical fit.

Crystals Selection Notes

Select this component when high stability is required within a compact form factor. The ±10 ppm tolerance at room temperature distinguishes it from standard ±30 ppm crystals. Consider the 50 Ohm ESR for oscillator circuit compatibility. The seam seal technology offers advantages over ceramic packages in harsh environments where moisture resistance is critical.

Crystals Part Context

This part belongs to the TXC MHz Quartz Crystal family, characterized by seam seal packaging. It serves as a high-precision alternative to standard ceramic or silver electrode crystals. The 7M series targets applications demanding superior frequency accuracy and long-term stability compared to general-purpose timing components.
