Crystals Procurement Notes

Verify the exact operating temperature range and moisture sensitivity classification against the official manufacturer datasheet before integration. Confirm that the specified load capacitance matches the oscillator circuit design requirements to ensure accurate frequency performance. Check for any specific handling precautions related to the surface-mount package type during assembly processes.

Crystals Selection Notes

Select this component when a standard 25 MHz reference with moderate stability requirements is needed. Ensure the application environment stays within the specified temperature limits. Verify that the PCB layout accommodates the specific 6.00 mm by 3.50 mm package dimensions and that the target impedance aligns with the 10 pF load capacitance specification.

Crystals Part Context

This component belongs to the CTS 406 series of surface-mount crystals. It serves as a passive frequency-determining element rather than an active oscillator. Unlike the CA25 or CA50 series found in other records, this part requires an external oscillator circuit to generate a square wave output.
