8Z-27.000MEEQ-T

Crystals Overview

The 8Z-27.000MEEQ-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a fundamental frequency of 27.000 MHz. It features a frequency stability and tolerance of ±10 ppm across an industrial temperature range of -20°C to +70°C. The component utilizes a load capacitance of 10 pF and exhibits an equivalent series resistance (ESR) of 60 Ohms. Physically, it is housed in a compact 4-SMD, No Lead package with dimensions of 2.5 mm x 2.0 mm x 0.55 mm. This unit is designed for high precision and high-frequency stability applications requiring seam-sealed construction.

Crystals Procurement Notes

Verify the specific suffix and manufacturer part number against official TXC documentation to confirm exact electrical parameters and packaging. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Check for RoHS compliance status and availability constraints, as supply chain conditions may vary. Confirm that the selected variant meets the required thermal and frequency stability specifications for the target application environment before finalizing procurement.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal with tight ±10 ppm stability is required. The 10 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR value for impedance matching. The small 2.5x2.0 mm package is ideal for dense layouts. Verify that the -20°C to +70°C operating range covers the intended environmental conditions. Compare against alternative series like 7M if larger packages are acceptable.

Crystals Part Context

This part belongs to the TXC 8Z series of surface-mount crystals, characterized by seam-sealed technology for enhanced durability. It operates at the standard 27 MHz frequency commonly used in video and data processing applications. The series offers various tolerance and load capacitance options. The 8Z-27.000MEEQ-T specifically provides high accuracy within a compact form factor, distinguishing it from larger through-hole or standard SMD crystals.

Crystals Replacement Considerations

The 7M-27.000MEEQ-T is a comparable alternative from TXC but uses a larger 3.2x2.5 mm package. Verify pinout compatibility and mechanical clearance before substitution. Other manufacturers may offer similar 27 MHz crystals, but load capacitance and ESR values must be matched to ensure circuit oscillation stability.
