7M-40.000MAHI-T

Crystals Overview

The 7M-40.000MAHI-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 40 MHz with a frequency stability and tolerance of ±30 ppm across an industrial temperature range of -40°C to +85°C. The component utilizes a 16 pF load capacitance and exhibits an equivalent series resistance (ESR) of 60 Ohms. Housed in a compact 4-SMD, no-lead package measuring 3.20 mm in length, 2.50 mm in width, and 0.80 mm in maximum height, it supports base harmonic operation mode. This device complies with RoHS3 standards and carries an EAR99 classification.

Crystals Feature Summary

• Provides stable 40 MHz oscillation with ±30 ppm frequency tolerance
• Operates reliably within the -40°C to +85°C industrial temperature range
• Features a low-profile 4-SMD no-lead surface mount package
• Designed for base harmonic operation with 16 pF load capacitance

Crystals Applications

• Precision clock generation in digital communication systems
• Timing references for microcontrollers and processors
• Synchronization circuits in consumer electronics
• Industrial control system timing modules

Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when placing orders. Confirm that the 16 pF load capacitance matches the target circuit design requirements. Ensure compatibility with standard SMT reflow processes given the 4-SMD no-lead form factor. Check current availability status as supply levels may fluctuate. Validate that the ±30 ppm stability meets the system's jitter and phase noise specifications.

Crystals Selection Notes

Select this component when a 40 MHz reference with moderate stability is required in a small footprint. Compare against the 7M-40.000MAHV-T variant which uses 8 pF load capacitance; choose based on oscillator circuit design constraints. Consider the 60 Ohm ESR value for drive level sensitivity analysis. Ensure the operating temperature range covers the intended environmental conditions. Verify package dimensions fit within the PCB layout constraints.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation, which offers various frequencies and packages. The 7M series is characterized by its small size and reliability for general-purpose timing applications. The MAHI-T designation specifies the 40 MHz frequency, 16 pF load, and reel packaging. It serves as a fundamental resonator for generating precise clock signals in embedded systems.

Crystals Replacement Considerations

The 7M-40.000MAHV-T is a parameter-equivalent alternative within the same series but differs in load capacitance (8 pF vs. 16 pF). Direct substitution requires verifying the oscillator circuit's capacitive load matching. No other cross-manufacturer substitutes are confirmed in the provided documentation.
