7M-37.500MEEE-T

Crystals Overview

The 7M-37.500MEEE-T is a seam-sealed MHz quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 37.5 MHz with a tolerance of ±10 ppm at 25°C and ±10 ppm over the -20°C to +70°C temperature range. The component utilizes a 4-SMD, No Lead package with dimensions of 3.2 mm x 2.5 mm. It features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 50 Ohms.

Crystals Feature Summary

• Seam-sealed construction using ceramic materials for enhanced environmental stability
• Low profile surface-mount design suitable for automated assembly processes
• Standard CMOS-compatible output characteristics for digital clocking applications

Crystals Applications

• General-purpose digital clock signal generation
• Microcontroller and microprocessor timing references
• Communication equipment synchronization circuits

Crystals Procurement Notes

Verify the specific manufacturing lot date code against project requirements, as this component may be subject to production lifecycle changes. Confirm that the 4-SMD no-lead footprint matches the PCB layout constraints. Ensure that the ±10 ppm frequency stability meets the system timing budget under all operating temperature conditions within the specified commercial range.

Crystals Selection Notes

Select this component when a compact, seam-sealed quartz crystal is required for 37.5 MHz applications. The 12 pF load capacitance must align with the oscillator circuit design. Consider the 50 Ohm ESR value for drive level optimization. This part is suitable for commercial temperature ranges (-20°C to +70°C) where standard stability is sufficient.

Crystals Part Context

This part belongs to the 7M series of MHz quartz crystals from TXC Corporation. These components are characterized by their small form factor and reliability in consumer and industrial electronics. The series offers various frequency options within the MHz range, providing designers with standardized solutions for high-frequency timing needs in space-constrained designs.

Crystals Replacement Considerations

Direct substitutes include other 37.5 MHz crystals with identical 3.2x2.5 mm dimensions, 12 pF load capacitance, and ±10 ppm stability. Verify that alternative manufacturers offer comparable ESR values and seam-sealed construction to ensure mechanical and electrical compatibility.
