8Y-37.400MEEC-T

Crystals Overview

The 8Y-37.400MEEC-T is a seam-sealed MHz quartz crystal resonator manufactured by TXC Corporation. It operates at a fundamental frequency of 37.4 MHz with a frequency stability and tolerance of ±10 ppm. The component features a load capacitance of 9 pF and an equivalent series resistance (ESR) of 80 Ohms. Designed for surface mount applications, it utilizes a 4-SMD, no-lead package with dimensions of 2.0 mm in length, 1.6 mm in width, and a maximum height of 0.50 mm. The device supports a base harmonic operating mode and functions within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Seam-sealed construction for enhanced environmental protection
• High frequency stability with ±10 ppm tolerance
• Compact 4-SMD no-lead surface mount footprint

Crystals Applications

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

Crystals Procurement Notes

Verify the specific load capacitance requirement of 9 pF against the target circuit design to ensure accurate frequency performance. Confirm that the operating temperature range of -20°C to +70°C aligns with the intended application environment. Ensure the PCB layout accommodates the 2.0 x 1.6 mm SMD package dimensions and appropriate soldering profiles for seam-sealed crystals.

Crystals Selection Notes

Select this component when a compact, high-stability quartz solution is required for 37.4 MHz applications. The 9 pF load capacitance distinguishes it from standard 10 pF or 12.5 pF variants, necessitating careful impedance matching. Consider the seam-sealed technology for improved reliability compared to standard epoxy-sealed alternatives in demanding environments.

Crystals Part Context

This part belongs to the 8Y series of MHz quartz crystals from TXC Corporation. The series is characterized by small form factors and high accuracy, suitable for modern electronic devices requiring precise timing in limited space. The 8Y designation indicates a specific package style and manufacturing process optimized for high-volume surface mount assembly.

Crystals Replacement Considerations

The 8Z-19.200MEEQ-T is listed as a similar alternative by the manufacturer, though it differs in frequency and series characteristics. Direct substitution requires verification of electrical parameters including load capacitance and ESR.
