8Z-37.400MAAJ-T

Crystals Overview

The TXC Corporation 8Z-37.400MAAJ-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 37.4 MHz. It features a frequency tolerance of ±30 ppm and a load capacitance of 18 pF. The component exhibits an equivalent series resistance (ESR) of 60 Ohms and operates within a temperature range of -40°C to +85°C. Its physical dimensions are 2.5 mm in length, 2.0 mm in width, and 0.55 mm in height, housed in a compact 4-SMD, no-lead package designed for automated assembly processes.

Crystals Feature Summary

• Seam seal construction ensures long-term frequency stability and environmental robustness.
• Compact 4-SMD no-lead footprint facilitates efficient surface-mount placement.
• Fundamental mode operation provides precise timing reference at 37.4 MHz.

Crystals Applications

• Microcontroller clock sources requiring stable timing references.
• Communication modules utilizing 37.4 MHz carrier or intermediate frequencies.
• Consumer electronics with space-constrained printed circuit board layouts.

Crystals Procurement Notes

Verify the specific suffix 'MAAJ' against the manufacturer's current part number guide to confirm active status and availability. Ensure the ordering documentation explicitly matches the 8Z-37.400MAAJ-T designation to avoid confusion with similar variants in the 8Z series that may differ in tolerance or packaging specifications.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with ±30 ppm initial tolerance. The 18 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR limit for drive level sensitivity. The -40°C to +85°C industrial temperature range suits general electronic applications beyond standard commercial limits.

Crystals Part Context

This part belongs to the TXC 8Z series of seam-sealed quartz crystals. The series is characterized by small form factors suitable for modern portable devices. The 8Z-37.400MAAJ-T specifically targets applications needing a 37.4 MHz output with moderate stability requirements in a leadless SMD package.

Crystals Replacement Considerations

Direct substitutes include other 37.4 MHz crystals with matching 18 pF load capacitance and compatible ESR values. Verify that alternative parts support the same 4-SMD no-lead mechanical outline and meet the -40°C to +85°C temperature specification.
