8Y-27.120MAHJ-T

Crystals Overview

The TXC Corporation 8Y-27.120MAHJ-T is a quartz crystal unit operating at a nominal frequency of 27.12 MHz. It utilizes an AT-cut thickness shear mode and is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 mm x 1.6 mm x 0.6 mm. The component features a load capacitance of 18 pF and a maximum shunt capacitance of 3 pF. Frequency stability is maintained within ±30 ppm over the operating temperature range of -20°C to +70°C. The equivalent series resistance (ESR) is specified at 100 Ohms.

Crystals Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• AT-cut resonator technology ensuring stable oscillation performance
• RoHS compliant construction supporting environmentally friendly manufacturing

Crystals Applications

• RFID reader modules
• ISM band communication devices
• Portable medical equipment
• Short-range wireless transceivers

Crystals Procurement Notes

Verify that the specific suffix 'J' corresponds to the required 18 pF load capacitance and 100 Ohm ESR specifications for your circuit design. Confirm that the 2.0x1.6mm footprint matches the target PCB land pattern. Ensure the operating temperature range of -20°C to +70°C aligns with the environmental conditions of the final assembly. Cross-reference the datasheet to confirm RoHS compliance status for regulatory requirements.

Crystals Selection Notes

Select this component when a small form factor is critical for the application. The 27.12 MHz frequency is standard for ISM band operations. Consider the 100 Ohm ESR value against the oscillator circuit's drive level capabilities. Compare against other 8Y series variants if different load capacitances or temperature ranges are required. Ensure the SMD package height fits within the mechanical clearance constraints of the enclosure.

Crystals Part Context

This part belongs to the TXC 8Y series of miniature quartz crystals. The series is characterized by its small 2.0x1.6mm footprint, making it distinct from larger 3.2x2.5mm packages like the 7M or 7V series. The 8Y series is designed for high-volume consumer electronics where board space is limited. It shares the same fundamental AT-cut technology but differs in physical dimensions and electrical parameters compared to other TXC crystal families.

Crystals Replacement Considerations

Direct substitutes include the 8Y-27.120MAHQ-T, which offers AEC-Q200 automotive qualification. Other compatible options may include parts from QST or NDK with identical 27.12 MHz frequency, 18 pF load capacitance, and 2.0x1.6mm package dimensions. Verify ESR and shunt capacitance values before substitution.
