• Real-time clock modules
• Low-power embedded systems requiring precise frequency reference

Crystals Procurement Notes

Verify the specific suffix '-E' against the manufacturer's official datasheet to confirm the exact temperature range and tolerance specifications, as suffixes often denote variations in performance or packaging. Ensure the ordering documentation explicitly matches the part number to avoid discrepancies in electrical parameters or physical dimensions during procurement.

Crystals Selection Notes

Select this component when a through-hole cylindrical crystal is required for 32.768 kHz applications. Consider the 12.5 pF load capacitance requirement for circuit design compatibility. Evaluate the ±20 ppm tolerance against system timing accuracy needs. Confirm that the 35 kOhm ESR value aligns with the oscillator circuit's drive capability constraints.

Crystals Part Context

This part belongs to the AB26T series of cylindrical watch crystals from Abracon. These components are standard solutions for providing stable frequency references in battery-operated devices where space efficiency and reliable through-hole integration are prioritized over surface-mount alternatives.

Crystals Replacement Considerations

Cross-reference with other Abracon cylindrical crystals such as the WC26F series for similar form factors. Verify mechanical dimensions and electrical parameters before substituting with generic equivalents to ensure circuit compatibility.
