Crystals Procurement Notes

Verify the specific ESR value against circuit requirements, as datasheet variations may list 60 Ohms or 150 Ohms for this series. Confirm the package footprint matches the 5.00mm x 3.20mm dimension. Ensure the ±30ppm tolerance meets system phase noise specifications. Check RoHS compliance status if required by project regulations.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required in a compact SMD form factor. The 20pF load capacitance must match the oscillator circuit design. Consider the 150 Ohm ESR limit for drive level sensitivity. The industrial temperature range suits applications exposed to environmental fluctuations beyond commercial limits.

Crystals Part Context

This part belongs to the 403 Series of crystals from CTS-Frequency Controls. The series offers various frequencies in standard SMD packages. The 'I' suffix typically denotes industrial temperature range performance. This specific model provides a balance between size and electrical performance for embedded systems.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz crystals with identical 20pF load capacitance and similar ESR values. Verify that alternative parts support the same 4-SMD 5.00x3.20mm footprint. Ensure replacement components meet the -40°C to +85°C operating temperature specification.
