7V-27.000MDDV-T

Crystals Overview

The TXC Corporation 7V-27.000MDDV-T is a surface-mount crystal oscillator operating at a fundamental frequency of 27 MHz. It features an 8 pF load capacitance and a frequency tolerance of ±20 ppm. The component utilizes a 4-SMD, No Lead package with dimensions of 3.2 mm x 2.5 mm and a maximum height of 0.7 mm. It exhibits an equivalent series resistance (ESR) of 60 Ohms and supports an operating temperature range from -20°C to +70°C.

Crystals Feature Summary

• Provides stable 27 MHz timing signals for digital circuits
• Designed for surface-mount assembly via SMD/No Lead configuration
• Complies with RoHS standards for lead-free manufacturing

Crystals Applications

• Clock generation in consumer electronics
• Timing references in automotive infotainment systems
• Signal synchronization in industrial control modules

Crystals Procurement Notes

Verify the specific suffix and package dimensions against the official datasheet to ensure compatibility with the target PCB footprint. Confirm that the 8 pF load capacitance matches the circuit design requirements. Check for AEC-Q200 certification if the application demands automotive-grade reliability standards beyond standard commercial specifications.

Crystals Selection Notes

Select this component when a compact 27 MHz reference is required for space-constrained designs. Ensure the system oscillator circuit is tuned for an 8 pF load to achieve the specified ±20 ppm accuracy. Consider the -20°C to +70°C operating range to verify suitability for the intended environmental conditions without requiring extended temperature variants.

Crystals Part Context

This part belongs to the TXC crystal family, specifically designed as a passive resonator element rather than an active oscillator. It requires an external oscillator circuit to function. The 7V series denotes a specific size and performance tier within the manufacturer's portfolio of surface-mount crystals.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz crystals with identical 8 pF load capacitance and 4-SMD no-lead packaging. Verify that alternative parts match the 60 Ohm ESR specification and the ±20 ppm tolerance to maintain signal integrity.
