8Q-37.400MDDE-T

Crystals Overview

The 8Q-37.400MDDE-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a nominal frequency of 37.4 MHz. It features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 80 Ohms. The component provides a frequency tolerance and stability of ±20 ppm at 25°C, with extended stability of ±20 ppm across the -20°C to +70°C operating temperature range. Housed in a compact 4-SMD, No Lead package measuring 1.6 mm x 1.2 mm x 0.40 mm, it utilizes seam seal technology for environmental protection.

Crystals Feature Summary

• Seam sealed ceramic construction for enhanced environmental durability
• Compact 4-SMD no-lead footprint suitable for space-constrained designs
• Base mode operation for stable frequency generation

Crystals Applications

• General purpose clock signal generation
• Microcontroller system timing references
• Embedded digital circuit synchronization

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design before procurement. Confirm that the ±20 ppm stability specification meets the application's timing accuracy needs. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the 80 Ohm ESR value with oscillator driver strength capabilities to prevent over-driving or failure.

Crystals Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 12 pF load capacitance must match the external capacitors used in the oscillator circuit. Consider the 80 Ohm ESR limit when evaluating power consumption and drive level constraints. This part is suitable for standard commercial applications where extreme precision is not critical.

Crystals Part Context

This model belongs to the 8Q series of high-accuracy MHz quartz crystals from TXC Corporation. The series offers various frequency and load capacitance options within the same 1.6 mm x 1.2 mm package. It serves as a cost-effective timing solution for consumer electronics and industrial control systems requiring reliable surface-mount components.

Crystals Replacement Considerations

Compatible substitutes include the 8Q-37.400MAAV-T and 8Q-37.400MEEC-T from TXC Corporation. These alternatives share similar specifications but may differ in load capacitance or tolerance. Verify electrical compatibility before substitution.
