8Q-40.000MEJE-T

Crystals Overview

The TXC Corporation 8Q-40.000MEJE-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 40 MHz. It utilizes a seam seal ceramic package with dimensions of 1.6 mm x 1.2 mm and a maximum height of 0.35 mm. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 80 Ohms. Frequency tolerance is specified at ±10 ppm at 25°C, with stability maintained within ±10 ppm across the industrial temperature range of -30°C to +85°C. The device supports a maximum drive level of 50 µW and is designed for SMD/SMT mounting applications.

Crystals Procurement Notes

Verify the specific suffix MEJE against official datasheets to confirm the exact temperature range and package variant, as TXC part numbering conventions may vary by region or revision. Confirm RoHS compliance status directly with the manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability certificates matching the original TXC Corporation manufacturing records.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required in space-constrained designs utilizing 1.6x1.2 mm footprints. The 12 pF load capacitance must match the oscillator circuit requirements. Consider the 80 Ohm ESR value for driver strength compatibility. Verify that the operational environment remains within the -30°C to +85°C range to maintain the specified ±10 ppm stability.
