7R-38.400MDIQ-T

Crystals Overview

The TXC Corporation 7R-38.400MDIQ-T is a surface-mount MHz quartz crystal designed for precision timing applications. It operates at a nominal frequency of 38.4 MHz with a load capacitance of 10 pF. The component exhibits high frequency stability, specified at ±20 ppm at 25°C and ±20 ppm across the industrial temperature range of -40°C to +85°C. Housed in a compact 2.0 x 1.6 mm ceramic package with four solder pads, it utilizes a glass seal construction to ensure environmental robustness and long-term reliability.

Crystals Feature Summary

• Glass-sealed ceramic construction for enhanced durability
• Compact 2.0 x 1.6 mm SMD footprint
• High frequency stability within industrial temperature ranges

Crystals Applications

• Precision clock generation in embedded systems
• Timing references for microcontrollers and processors
• Communication interface synchronization circuits

Crystals Procurement Notes

Verify the specific suffix 'IQ' against official datasheets to confirm the exact tolerance and temperature specifications, as minor variations may exist between revisions. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a small form factor is required alongside strict frequency stability. The 10 pF load capacitance must match the oscillator circuit design. Consider the -40°C to +85°C operating range suitability for the intended environment compared to commercial or extended temperature alternatives.

Crystals Part Context

This part belongs to the TXC Corporation series of surface-mount crystals. It serves as a passive timing element, distinct from active oscillators. The 7R series typically denotes specific package dimensions and sealing technologies, providing a balance between size constraints and performance metrics for consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include other 38.4 MHz crystals with identical 10 pF load capacitance and compatible 2.0 x 1.6 mm packages. Verify that alternative manufacturers offer matching ±20 ppm stability and similar ESR values to ensure circuit compatibility without redesign.
