7M-48.000MAHQ-T

Crystals Overview

The 7M-48.000MAHQ-T is a fundamental parallel resonant quartz crystal manufactured by TXC Corporation, operating at a nominal frequency of 48 MHz. It utilizes a ceramic package with seam seal construction and measures 3.2 mm x 2.5 mm x 0.7 mm. The component supports a load capacitance of 10 pF and maintains a frequency stability of +/-30 ppm across the industrial temperature range of -40°C to +85°C. It features a maximum equivalent series resistance (ESR) of 60 Ohms and operates with an input drive level of 1 mW.

Crystals Feature Summary

• Seam seal ceramic construction for enhanced environmental protection
• Fundamental parallel resonance operation mode
• Industrial temperature range stability specification

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• Digital signal processing circuits

Crystals Procurement Notes

Verify the specific suffix 'HQ' against official TXC documentation to confirm the seam seal package type and exact electrical tolerances. Ensure the target circuit design accommodates the specified 10 pF load capacitance and 1 mW drive level requirements for reliable operation.

Crystals Selection Notes

Select this component when a robust ceramic package is required for industrial environments. The 48 MHz frequency is suitable for USB or Ethernet interfaces. Confirm that the PCB footprint matches the 3.2x2.5 mm dimensions and that the oscillator circuit is designed for the specified ESR and load capacitance values.

Crystals Part Context

This part belongs to the 7M series of MHz quartz crystals from TXC Corporation. It is distinguished by its seam seal ceramic housing, which offers superior moisture resistance compared to standard metal can packages. The series provides stable timing solutions for compact electronic designs requiring high reliability.

Crystals Replacement Considerations

The 7M-48.000MAHC-T is a documented alternative within the same series, featuring identical dimensions but differing in load capacitance (9 pF vs 10 pF). Verify circuit compatibility regarding load capacitance before substitution.
