7A-27.000MDDV-T

Crystals Overview

The 7A-27.000MDDV-T is a fundamental mode crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 27 MHz with a load capacitance of 8 pF and a frequency tolerance of ±20 ppm. The component features an equivalent series resistance (ESR) of 50 Ohms and utilizes a compact 2-SMD, No Lead package measuring 5.00 mm in length and 3.20 mm in width.

Crystals Feature Summary

• Fundamental oscillation mode operation
• Compact two-terminal surface-mount design
• High stability frequency generation

Crystals Applications

• Precision timing circuits
• Frequency reference sources
• Embedded system clocking

Crystals Procurement Notes

Verify the specific AEC-Q200 automotive qualification status directly with the manufacturer or authorized distributors, as public documentation for this exact part number does not explicitly confirm this certification level. Ensure that the 2-SMD footprint matches the target PCB layout requirements before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 8 pF load capacitance specification must align with the host oscillator circuit design to ensure accurate frequency performance. Consider the 50 Ohm ESR value for impedance matching within the application environment.

Crystals Part Context

This model belongs to the 7A series of crystals from TXC Corporation, which focuses on miniature passive components. The series provides reliable frequency control solutions for consumer electronics and industrial equipment where space constraints are critical. It serves as a basic timing element rather than an active oscillator.

Crystals Replacement Considerations

The 7A-27.000MDDV-T is functionally similar to the 7A-27.000MAAE-T and 7A-27.000MAAJ-T regarding frequency and package dimensions. However, these alternatives may differ in load capacitance values and operating temperature ranges. Verify electrical compatibility before substitution.
