7M-40.000MAHQ-T

Crystals Overview

The 7M-40.000MAHQ-T is a 40 MHz quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It features a frequency stability of ±30ppm and operates within a temperature range of -40°C to +85°C. The component utilizes a 10pF load capacitance and exhibits an equivalent series resistance (ESR) of 50 Ohms. Housed in a compact 4-SMD, No Lead package with dimensions of 3.2mm x 2.5mm, it supports fundamental mode operation.

Crystals Feature Summary

• Surface-mount design compatible with automated assembly processes
• Fundamental mode vibration for stable frequency generation
• Compact footprint suitable for space-constrained circuit boards

Crystals Applications

• General-purpose clock signal generation
• Microcontroller timing circuits
• Communication module synchronization

Crystals Procurement Notes

Verify the specific suffix HQ against official datasheets to confirm load capacitance and ESR values. Ensure compatibility with PCB footprints matching the 3.2mm x 2.5mm SMD package. Confirm RoHS compliance status through current manufacturer documentation before integration.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±30ppm stability is required. The 10pF load capacitance must match the oscillator circuit design. Consider the 50 Ohm ESR for drive level limitations. The wide temperature range supports industrial environments.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation. The series offers various frequency options and package sizes. The 7M-40.000MAHQ-T specifically addresses needs for reliable 40 MHz timing in standard surface-mount layouts.

Crystals Replacement Considerations

Cross-reference with 7M-40.000MAHV-T or 7M-40.000MAHE-T only if electrical parameters align. Verify that alternative suffixes match the required 10pF load capacitance and 50 Ohm ESR specifications.
