8Z-27.120MAAJ-T

Crystals Overview

The TXC CORPORATION 8Z-27.120MAAJ-T is a passive quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 27.12 MHz with a frequency tolerance of ±30 ppm. The component features an 18 pF load capacitance and a maximum equivalent series resistance (ESR) of 100 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 3.2 mm in length, 2.5 mm in width, and 0.8 mm in height. The device supports a standard operating temperature range from -20°C to +70°C.

Crystals Feature Summary

• Surface-mount passive quartz crystal resonator
• Miniature 4-SMD no-lead package design
• Standard frequency stability of ±30 ppm

Crystals Applications

• Clock signal generation in microcontroller circuits
• RF transmitter and receiver modules
• Wireless communication devices

Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required by automated assembly processes. Confirm that the 100 Ohm ESR limit aligns with the oscillator circuit's drive level requirements to prevent over-driving the crystal. Ensure the 18 pF load capacitance matches the external capacitors specified in the host system schematic for accurate frequency calibration.

Crystals Selection Notes

Select this component when a 27.12 MHz reference is required for SMD manufacturing. The 100 Ohm ESR specification is critical for compatibility with low-power oscillator designs. Compare against the 7V series if a smaller 3.2x2.5mm footprint with different electrical characteristics is needed. Verify that the ±30 ppm stability meets the timing accuracy constraints of the target application.

Crystals Part Context

This part belongs to the TXC Corporation general-purpose crystal lineup. It serves as a fundamental timing element for digital systems requiring precise clock synchronization. The 8Z series designation typically denotes standard commercial-grade performance levels suitable for consumer electronics and industrial control applications where moderate stability is sufficient.
