7M-38.400MEEE-T

Crystals Overview

The 7M-38.400MEEE-T is a MHz quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 38.4 MHz with a high frequency stability of ±10 ppm at 25°C and ±10 ppm over the -20°C to +70°C temperature range. The component utilizes a seam seal package in a 4-SMD, no lead configuration, measuring 3.20 mm x 2.50 mm x 0.80 mm. It features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 60 Ohms. The device supports fundamental mode operation and is compliant with RoHS3 standards.

Crystals Feature Summary

• High frequency stability of ±10 ppm across specified operating temperatures
• Seam seal construction for enhanced environmental protection
• Compact 4-SMD surface-mount footprint suitable for automated assembly

Crystals Applications

• Precision timing circuits requiring stable clock references
• Embedded systems and microcontroller interfaces
• Communication equipment signal processing modules

Crystals Procurement Notes

Verify the specific load capacitance requirement of 12 pF against the target circuit design to ensure accurate oscillation. Confirm that the operating environment remains within the -20°C to +70°C range to maintain the guaranteed ±10 ppm stability. Ensure PCB layout accommodates the 3.2x2.5 mm SMD footprint and adheres to recommended soldering profiles for seam seal packages.

Crystals Selection Notes

Select this component when a balance of high accuracy and compact size is required for MHz-range applications. The ±10 ppm tolerance offers superior stability compared to standard crystals, making it suitable for sensitive digital interfaces. Consider the 12 pF load capacitance compatibility with the oscillator circuit's input capacitance to prevent frequency deviation.

Crystals Part Context

This part belongs to the 7M series of high-accuracy quartz crystals from TXC Corporation. The series is characterized by tight frequency tolerances and robust seam-seal packaging. It serves as a passive timing element distinct from active oscillators, relying on external oscillator circuits to generate square wave signals based on the mechanical resonance of the quartz resonator.
