8Y-27.120MAAV-T

Crystals Overview

The 8Y-27.120MAAV-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for fundamental mode operation at a nominal frequency of 27.12 MHz. It features an 8 pF load capacitance and maintains a frequency tolerance and stability of ±30 ppm across its operational range. The component utilizes a compact 4-SMD, no-lead package with dimensions of 3.20 mm in length, 2.50 mm in width, and a maximum height of 0.50 mm. It operates within a temperature range of -20°C to +70°C and complies with RoHS3 standards.

Crystals Feature Summary

• Fundamental oscillation mode ensures stable signal generation for RF applications.
• Compact 3.2x2.5 mm SMD footprint supports space-constrained PCB layouts.
• RoHS3 compliant construction meets environmental regulatory requirements.

Crystals Applications

• RFID tag systems
• ISM band short-range communication devices
• Medical equipment requiring precise timing

Crystals Procurement Notes

Verify the specific suffix 'AAV' against the official datasheet to confirm the 8pF load capacitance and 0.50mm height specifications. Ensure the procurement channel provides documentation confirming RoHS3 compliance and MSL Level 1 status. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit components.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required for ISM band or RFID applications. The 8pF load capacitance must match the circuit design's external capacitor values. Consider the -20°C to +70°C operating range suitability for the target environment. The low profile height facilitates dense surface mount assembly processes.

Crystals Part Context

This part belongs to the TXC 8Y series of ceramic crystals, which are optimized for small form factors. It shares the 27.12 MHz frequency point with other series members like the 7V and 8Z series but differs in physical dimensions and load capacitance specifications. The 8Y series specifically targets ultra-thin application requirements compared to standard 3.2x2.5 mm packages.

Crystals Replacement Considerations

QT325G-27.120MAHV-T from QST is listed as a parameter-equivalent substitute. Verify that the replacement matches the 8pF load capacitance and 3.2x2.5mm package dimensions before integration.
