7M-37.400MAHI-T

Crystals Overview

The 7M-37.400MAHI-T is a seam seal MHz quartz crystal manufactured by TXC Corporation. It operates at a fundamental frequency of 37.4 MHz with a frequency tolerance of ±30ppm at 25°C and ±30ppm over the -40 to +85°C temperature range. The component features a load capacitance of 16pF and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a 4-SMD, no lead package with dimensions of 3.2mm x 2.5mm and a maximum height of 0.8mm. Designed for surface mount applications, it supports base harmonic operation mode.

Crystals Feature Summary

• Seam seal construction for enhanced environmental stability
• Compact 3.2mm x 2.5mm surface mount footprint
• Wide operating temperature range from -40°C to +85°C

Crystals Applications

• General purpose clock signal generation
• Microcontroller system timing references
• Communication interface circuits

Crystals Procurement Notes

Verify the specific suffix HI against official datasheets to confirm the exact load capacitance and ESR values, as variations exist within the 7M series. Ensure the ordering documentation explicitly states the 16pF load capacitance requirement to match the circuit design. Confirm the package dimensions align with the PCB footprint specifications provided in the manufacturer's drawing.

Crystals Selection Notes

Select this component when a 37.4 MHz reference is required with moderate stability requirements. The 16pF load capacitance must be compatible with the oscillator circuit design. Consider the 50 Ohm ESR value for drive level sensitivity. The wide temperature range makes it suitable for industrial environments where standard commercial grade crystals may fail.

Crystals Part Context

This part belongs to the 7M series of seam seal quartz crystals from TXC Corporation. The series offers various frequencies and package sizes. The 7M-37.400MAHI-T specifically targets applications needing a stable 37.4 MHz signal in a small form factor. It is distinct from oscillators or TCXOs, functioning as a passive resonator requiring an external oscillator circuit.
