8Q-37.400MDDV-T

Crystals Overview

The 8Q-37.400MDDV-T is a fundamental mode quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 37.4 MHz with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 80 Ohms. The component provides a frequency tolerance and stability of ±20 ppm across an operating temperature range of -20°C to +70°C. It utilizes a 4-SMD, No Lead package with dimensions of 1.60 mm in length, 1.20 mm in width, and a maximum height of 0.40 mm.

Crystals Feature Summary

• Fundamental mode operation ensures stable oscillation characteristics.
• Compact 4-SMD no-lead package facilitates automated surface-mount assembly.
• Compliant with RoHS3 standards for environmental safety.

Crystals Applications

• General-purpose clock generation for digital circuits
• Timing references in consumer electronics
• Embedded systems requiring standard frequency stability

Crystals Procurement Notes

Verify the specific suffix 'MDDV' against the official TXC datasheet to confirm the exact tolerance and stability ratings, as variations exist within the 8Q series. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Confirm that the specified operating temperature range meets the thermal constraints of the final application environment before procurement.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 37.4 MHz applications with moderate stability needs. The 80 Ohm ESR must be compatible with the oscillator circuit's drive level specifications. Consider the ±20 ppm stability if tighter tolerances are not critical. Evaluate the 8 pF load capacitance requirement against the host system's input capacitance to ensure accurate frequency tuning.

Crystals Part Context

This part belongs to the 8Q series of high-accuracy MHz crystals from TXC Corporation. The series offers various frequency options and package sizes tailored for compact electronic designs. The 8Q-37.400MDDV-T specifically addresses the need for a reliable timing source in space-constrained devices where fundamental mode operation is preferred over overtone modes.

Crystals Replacement Considerations

The 8Q-37.400MAAV-T is listed as a similar alternative from TXC Corporation. Verify electrical compatibility, particularly regarding ESR and load capacitance, before substitution. Other manufacturers may offer functionally equivalent crystals, but pinout and dimensional tolerances must be confirmed to ensure mechanical fit.
