FO7HHADE40.0-T1

Oscillators Overview

The Fox Electronics FO7HHADE40.0-T1 is a surface-mount HCMOS crystal oscillator in a 7mm x 5mm package. It operates at a frequency of 40MHz with a stability of ±25ppm. The device supports a supply voltage of 5V±10% and functions within an industrial temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Industrial-grade wide temperature operation from -40°C to +85°C
• HCMOS output compatible with standard digital logic levels
• Standard 7mm x 5mm SMD footprint for board compatibility

Oscillators Applications

• Industrial data acquisition gateways
• Microcontroller clock sources
• Ethernet PHY timing references

Oscillators Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm active status and lead times. Ensure the 5V supply requirement aligns with the target system design, as this model does not support lower voltage options like 3.3V or 1.8V.

Oscillators Selection Notes

Select this component when a 5V supply is mandatory and ±25ppm stability suffices. For tighter tolerance requirements, consider models with 'E' suffixes offering ±20ppm. Verify power consumption limits against the system's LDO capabilities, as higher frequencies in this series draw significant current.

Oscillators Part Context

This part belongs to the FO7HH series, formerly designated as F3345. It serves as a direct replacement for legacy industrial oscillators while maintaining the 7x5mm form factor. The series provides robust performance for outdoor and harsh environment applications requiring stable timing signals.

Oscillators Replacement Considerations

Direct pin-compatible replacements include other variants within the FO7HH series sharing the 7x5mm package. Verify that substitute parts match the 5V supply voltage and HCMOS output characteristics to ensure seamless integration without circuit modification.
