8Y-27.120MAAE-T

Crystals Overview

The 8Y-27.120MAAE-T is a quartz crystal resonator manufactured by TXC Corporation, operating at a fundamental frequency of 27.12 MHz. It features a load capacitance of 12 pF and a frequency stability of ±30 ppm. The component has an equivalent series resistance (ESR) of 100 Ohms and a maximum shunt capacitance of 3 pF. Designed for surface-mount applications, it utilizes a compact 4-SMD, No Lead package with dimensions of 2.0 mm x 1.6 mm x 0.5 mm. The device supports a base harmonic mode and operates within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Compact 2.0x1.6mm surface-mount footprint suitable for space-constrained designs
• RoHS compliant and lead-free construction
• Fundamental mode operation with low shunt capacitance

Crystals Applications

• General purpose clock generation circuits
• Microcontroller oscillator inputs
• Consumer electronic timing references

Crystals Procurement Notes

Verify the specific package dimensions against your PCB footprint, as this model uses a 2.0x1.6mm case which differs from common 3.2x2.5mm variants. Confirm that the 100 Ohm ESR value aligns with your oscillator circuit design requirements. Ensure compatibility with the -20°C to +70°C operating temperature range for your intended application environment.

Crystals Selection Notes

Select this component when a small form factor is required alongside standard 27.12 MHz timing needs. Compare the 100 Ohm ESR against other options like the 7V series if lower impedance is necessary. Consider the 12 pF load capacitance requirement to ensure proper frequency matching with your host circuit's capacitive load.

Crystals Part Context

This part belongs to the TXC 8Y series of ceramic crystals. Unlike the larger 7V series components often found in similar catalogs, the 8Y series offers a reduced physical size of 2.0x1.6mm. It shares similar electrical characteristics such as frequency and stability but targets applications where board real estate is limited.

Crystals Replacement Considerations

The QT325G-27.120MAHV-T from QST is listed as a parameter-equivalent substitute. Note that while frequencies match, verify package dimensions and ESR values carefully before substitution.
