Crystals Procurement Notes

Verify the specific suffix 'CT' against manufacturer documentation to confirm tape and reel packaging specifications and moisture sensitivity levels. Ensure the order matches the exact load capacitance and ESR requirements of the target circuit design, as variations in suffixes may indicate different packaging or testing standards.

Crystals Selection Notes

Select this component when a 5 MHz reference is required for applications demanding operation up to 125°C. The 110 Ohm ESR and 12 pF load capacitance must align with the oscillator circuit's drive level and loading requirements to ensure stable frequency generation without overdriving the crystal.

Crystals Part Context

This part belongs to the HKC crystal oscillator family, specifically utilizing the standard HC-49S form factor. These components are designed for general-purpose timing applications where reliability across extended temperature ranges is critical, serving as primary clock sources for digital logic and communication interfaces.

Crystals Replacement Considerations

The 49SMSS0500BMDAFEGKF-TR is a related variant with identical electrical parameters but potentially different packaging. Verify mechanical footprint compatibility and soldering profile requirements before substitution.
