7M-12.000MEDQ-T

Crystals Overview

The TXC CORPORATION 7M-12.000MEDQ-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 12 MHz. It features a ±10 ppm frequency tolerance at 25°C and ±20 ppm over the -20°C to 70°C temperature range. The component utilizes a 10 pF load capacitance and has a maximum equivalent series resistance (ESR) of 80 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm x 0.80mm.

Crystals Feature Summary

• Seam seal construction for enhanced environmental stability
• High frequency accuracy with ±10 ppm initial tolerance
• Compact surface-mount footprint suitable for space-constrained designs

Crystals Applications

• Precision timing circuits requiring tight frequency stability
• Microcontroller clock sources
• Communication equipment baseband processing

Crystals Procurement Notes

Verify the specific suffix MEDQ against the official TXC ordering guide to ensure correct tolerance and packaging specifications. Confirm that the 10pF load capacitance matches the target circuit design requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when strict frequency accuracy is required within a limited temperature window. Ensure the application circuit supports the 10pF load capacitance and can handle the 80 Ohm ESR limit for reliable oscillation startup.

Crystals Part Context

This part belongs to the 7M series of seam seal crystals from TXC Corporation. These components are designed for general-purpose applications where higher stability than standard crystals is needed but full oscillator integration is not required.

Crystals Replacement Considerations

Consider the 7M-12.000MAAE-T if a ±30 ppm tolerance is acceptable. Verify package compatibility and load capacitance differences when substituting with other manufacturers' 12 MHz SMD crystals.
