8Q-40.000MEEV-T

Crystals Overview

The 8Q-40.000MEEV-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation, designed for high-precision timing applications. It operates at a fundamental frequency of 40.000 MHz with a frequency tolerance of ±10 ppm across the commercial temperature range of -20°C to +70°C. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 80 Ohms. Housed in a compact 4-SMD, No Lead package measuring 1.6 mm x 1.2 mm, it supports SMD/SMT mounting styles. This device provides stable clock signals for digital circuits requiring accurate frequency references within standard industrial operating conditions.

Crystals Procurement Notes

Verify the specific load capacitance requirement of 8 pF matches the host circuit design before procurement. Confirm that the operating temperature range of -20°C to +70°C aligns with the intended application environment. Ensure the 4-SMD, No Lead package dimensions fit the PCB layout constraints. Cross-reference the datasheet for any updates on RoHS compliance or material declarations prior to finalizing orders.

Crystals Selection Notes

Select this component when a 40 MHz frequency is required with moderate accuracy. Consider the 8 pF load capacitance compatibility with the oscillator circuit. Evaluate the 80 Ohm ESR against the driving capability of the target IC. The small form factor makes it suitable for dense PCB layouts where larger crystals cannot fit.

Crystals Part Context

This part belongs to the 8Q series of high-accuracy MHz crystals from TXC Corporation. The series offers various frequencies and packages optimized for consumer and industrial electronics. The 8Q-40.000MEEV-T specifically targets applications needing a stable 40 MHz reference in a minimal footprint, distinguishing it from larger through-hole or standard SMD crystals.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 8 pF load capacitance, and 4-SMD No Lead package. Verify ESR values around 80 Ohms and ±10 ppm tolerance. Check temperature range compatibility (-20°C to +70°C). Ensure pinout and footprint dimensions are identical to avoid rework.
