Crystals Procurement Notes

Verify the specific suffix 'I' against the manufacturer datasheet to confirm exact tolerance and stability specifications, as suffixes often denote critical performance variations. Ensure the ordering part number matches the required load capacitance and ESR values for the target circuit design. Confirm current availability status directly with authorized distributors, as stock levels fluctuate.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required in a small 5.00mm x 3.20mm surface mount package. The 8pF load capacitance and 60 Ohm ESR must match the oscillator circuit requirements. Verify that the ±20ppm tolerance meets the system's frequency accuracy needs across the specified -40°C to +85°C operating temperature range.

Crystals Part Context

This crystal belongs to the CTS 435 series, which offers various frequencies and packages. The 435F1202YIKT specifically provides a 12 MHz output in a standard 2-terminal SMD form factor. It serves as a passive frequency control element, distinct from active oscillators, requiring an external oscillator circuit to generate a square wave signal.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz crystals with identical 2-SMD dimensions, 8pF load capacitance, and 60 Ohm ESR. Verify pin compatibility and mounting orientation when replacing. Cross-reference with CTS part numbers such as 435F1202YCKT or 435F1202YIAT if parameter differences are acceptable.
