7M-27.120MEEQ-T

Crystals Overview

The 7M-27.120MEEQ-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 27.12 MHz with a load capacitance of 10 pF and an equivalent series resistance (ESR) of 50 Ohms. The component offers a frequency tolerance and stability of ±10 ppm. It is housed in a compact 3.2 mm x 2.5 mm SMD package with a maximum height of 0.7 mm. The device supports a standard operating temperature range from -20°C to +70°C and is supplied in tape and reel packaging.

Crystals Feature Summary

• Provides high-frequency stability with ±10 ppm tolerance and stability specifications.
• Features a low-profile 3.2 mm x 2.5 mm surface-mount footprint suitable for space-constrained designs.
• Operates on fundamental mode resonance with a 10 pF load capacitance requirement.

Crystals Applications

• Clock signal generation for microprocessors and microcontrollers
• Timing references for communication interfaces such as UART and SPI
• Frequency standards for consumer electronic devices

Crystals Procurement Notes

Verify the exact suffix 'MEEQ' to confirm the specific electrical parameters, particularly the 10 ppm stability and -20°C to +70°C temperature range. Ensure the design accounts for the 10 pF load capacitance and 50 Ohm ESR values. Confirm that the 3.2x2.5mm package dimensions align with the PCB footprint requirements. Check for RoHS compliance status if required by project specifications.

Crystals Selection Notes

Select this component when a stable 27.12 MHz reference is needed within a moderate temperature environment. The ±10 ppm accuracy is suitable for general digital logic and communication protocols. Consider the 0.7 mm height limit for assembly constraints. Compare against higher stability options if tighter tolerances are required or wider industrial temperature ranges are necessary for the application environment.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation, which focuses on small-sized surface-mount components. The series covers various frequencies and packages, providing standardized solutions for modern electronics. The 7M-27.120MEEQ-T specifically targets applications requiring reliable timing in consumer and industrial goods where space efficiency and cost-effectiveness are prioritized alongside performance.

Crystals Replacement Considerations

Direct substitutes may include other 27.12 MHz crystals with identical 3.2x2.5mm footprints and similar electrical characteristics. Verify compatibility regarding load capacitance and ESR to ensure circuit oscillation stability. Alternative parts from different manufacturers must match the pin configuration and physical dimensions for drop-in replacement.
