7M-40.000MAHC-T

Crystals Overview

The 7M-40.000MAHC-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a fundamental frequency of 40 MHz. It features a frequency stability and tolerance of ±30 ppm across an industrial temperature range of -40°C to +85°C. The component utilizes a 12 pF load capacitance and exhibits an equivalent series resistance (ESR) of 60 Ohms. Housed in a compact 4-SMD, no-lead package with dimensions of 3.20 mm x 2.50 mm x 0.80 mm maximum height, it supports base harmonic operation mode.

Crystals Feature Summary

• High precision frequency stability within the specified industrial temperature range
• Compact surface-mount design suitable for automated assembly processes
• Compliance with RoHS3 environmental standards

Crystals Applications

• General purpose clock signal generation in electronic circuits
• Timing reference for microcontrollers and digital logic systems
• Communication equipment requiring stable base frequency sources

Crystals Procurement Notes

Verify the specific suffix 'HC' against the official TXC Corporation datasheet to confirm exact load capacitance and dimensional tolerances. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 40 MHz fundamental mode crystal is required with ±30 ppm stability. The 12 pF load capacitance must match the oscillator circuit design specifications. Consider the 60 Ohm ESR value for impedance matching. The 3.2x2.5 mm footprint dictates PCB layout constraints compared to larger or smaller crystal packages.

Crystals Part Context

This part belongs to the 7M series of SMD seam sealing crystals from TXC Corporation. These units are characterized by high precision and high-frequency stability. The series offers various frequency options within a standardized small form factor, designed for reliable performance in consumer and industrial electronics applications requiring precise timing references.

Crystals Replacement Considerations

The AM-40.000MAHE-T is identified as a parameter-equivalent alternative within the TXC portfolio. Verify that the replacement matches the 12 pF load capacitance and 60 Ohm ESR specifications. Confirm that the substitute part maintains the same ±30 ppm stability and operates within the required -40°C to +85°C temperature range.
