7M-48.000METQ-T

Crystals Overview

The TXC Corporation 7M-48.000METQ-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 48 MHz. It features a frequency tolerance and stability of ±10 ppm across the commercial temperature range of -20°C to +70°C. The component utilizes a 10 pF load capacitance and exhibits an equivalent series resistance (ESR) of 50 Ohms with a maximum drive level of 100 µW. Housed in a compact 3.2 mm x 2.5 mm x 0.7 mm SMD package, it employs seam seal technology for environmental protection.

Crystals Feature Summary

• Seam seal construction provides enhanced environmental protection for the quartz element.
• Fundamental mode operation ensures stable oscillation at 48 MHz.
• Surface mount design facilitates automated assembly on printed circuit boards.

Crystals Applications

• Clock generation for microprocessors and microcontrollers
• Timing references for communication interfaces such as USB and Ethernet
• Synchronization circuits in consumer electronics

Crystals Procurement Notes

Verify the specific suffix 'METQ' against the manufacturer's official datasheet to confirm pinout, sealing method, and compliance status. Ensure the ordering part number matches the exact frequency tolerance and temperature range requirements of the target application. Cross-reference with authorized distributors to validate authenticity and traceability documentation before finalizing procurement.

Crystals Selection Notes

Select this component when a 48 MHz reference with ±10 ppm stability is required within a -20°C to +70°C operational window. The 10 pF load capacitance must align with the oscillator circuit design. Consider the 50 Ohm ESR and 100 µW drive level limits to ensure proper circuit startup and long-term reliability without overdriving the crystal.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation. The series is characterized by seam seal packaging, which offers superior moisture and contaminant resistance compared to standard epoxy-sealed crystals. This series is designed for applications requiring reliable timing performance in commercial electronic environments.

Crystals Replacement Considerations

The 7M-48.000MEEQ-T is a documented similar variant within the same product family. Verify that the ESR, load capacitance, and physical dimensions are compatible with the existing PCB footprint and circuit design before substitution.
