8Z-30.000MEHQ-T

Crystals Overview

The 8Z-30.000MEHQ-T is a fundamental mode quartz crystal resonator manufactured by TXC Corporation, operating at a nominal frequency of 30 MHz. It utilizes a 4-SMD, no lead surface-mount package with external dimensions of 2.50mm x 2.00mm and a maximum height of 0.55mm. The component features a load capacitance of 10pF and an equivalent series resistance (ESR) of 60 Ohms. Frequency tolerance is specified at ±10ppm at 25°C and ±30ppm across the industrial temperature range of -40°C to +85°C. It supports a drive level of up to 100µW typical.

Crystals Procurement Notes

Verify the specific suffix 'HQ' against the official TXC ordering guide to confirm the exact frequency tolerance and temperature range specifications. Ensure the design accommodates the 4-SMD no-lead footprint dimensions of 2.5x2.0mm. Confirm that the application circuit provides a drive level not exceeding 100µW to prevent frequency instability or damage. Check for any recent product change notices regarding this series.

Crystals Selection Notes

Select this component when a compact 30 MHz reference is required for space-constrained portable electronics. The 10pF load capacitance must match the oscillator circuit requirements. Consider the ±10ppm initial tolerance for systems requiring precise timing alignment. The industrial temperature range ensures reliability in varied environmental conditions compared to commercial grade alternatives.

Crystals Part Context

This part belongs to the 8Z series of high-accuracy MHz quartz crystals from TXC Corporation. The series is characterized by seam-sealed ceramic packages designed for surface mount applications. These components are engineered for use in digital communication systems where stable clock signals are critical for data integrity and synchronization.

Crystals Replacement Considerations

Direct substitutes include other 30 MHz crystals with identical 4-SMD 2.5x2.0mm footprints and 10pF load capacitance. Verify that alternative parts meet the same ±10ppm tolerance and 60 Ohm ESR specifications. Ensure the replacement maintains the fundamental mode operation and compatible drive level limits.
