8Z-37.400MAAE-T

Crystals Overview

The TXC Corporation 8Z-37.400MAAE-T is a surface-mount quartz crystal oscillator operating at a fundamental frequency of 37.4 MHz. It features a compact 2.5 mm x 2.0 mm seam-sealed package with a height of 0.55 mm. The component exhibits a load capacitance of 12 pF and an equivalent series resistance (ESR) of 80 Ohms. Frequency tolerance is specified at ±30 ppm at 25°C and ±30 ppm across the -20°C to +70°C operating temperature range. It utilizes a four-pad ceramic construction for SMD/SMT mounting.

Crystals Feature Summary

• Seam-sealed surface mount construction for enhanced environmental stability
• Compact 2.5x2.0 mm footprint suitable for space-constrained designs
• Four-pad ceramic termination for reliable SMD/SMT assembly

Crystals Applications

• Clock generation for microprocessors and microcontrollers
• Timing references in communication modules
• Frequency control in consumer electronic devices

Crystals Procurement Notes

Verify the specific suffix 'AAE' against official TXC documentation to confirm the -20°C to +70°C temperature range and 12pF load capacitance parameters. Ensure compatibility with reflow soldering profiles defined in the manufacturer's datasheet. Confirm RoHS compliance status as indicated in public listings, noting that some sources may list non-compliant variants for this series.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with ±30 ppm stability in industrial or commercial temperature ranges. The 12 pF load capacitance must match the oscillator circuit design. Consider the 80 Ohm ESR for drive level sensitivity. Compare against the 8Y series if extended temperature ranges are needed, though availability may vary.

Crystals Part Context

This part belongs to the TXC 8Z series of seam-sealed quartz crystals. These components are designed for high-frequency stability in surface-mount applications. The 8Z series typically offers robust performance in compact packages, distinguishing it from larger through-hole or standard SMD crystals. It serves as a timing reference where precise frequency accuracy is critical.

Crystals Replacement Considerations

Public data indicates the 8Y-37.400MAAE-T as a similar alternative within the TXC portfolio. Verify pinout compatibility and electrical parameter alignment before substitution. Note that the 7S-37.400MAAE-T is obsolete and not a direct replacement.
