Crystals Procurement Notes

Verify the specific suffix 'CAT' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the design accommodates the 4-SMD No Lead form factor and 10pF load capacitance requirements. Cross-reference the ESR value of 100 Ohms with circuit impedance matching needs before finalizing procurement.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental mode crystal is required with tight ±10 ppm tolerance. The 4-SMD package suits high-density PCB layouts. Verify that the application environment stays within the -20°C to +70°C operational range. Confirm that the 10pF load capacitance matches the oscillator circuit design parameters.

Crystals Part Context
