Crystals Procurement Notes

Verify the specific suffix 'XX' against official CTS documentation to confirm exact frequency code and tolerance specifications. Confirm current availability status as distribution channels may list discontinued or backorder items. Ensure the selected variant matches the required load capacitance and ESR for the target circuit design before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 26 MHz fundamental crystal with ±15ppm stability is required. Ensure the application circuit provides an 8pF load capacitance to maintain accuracy. Verify that the 100 Ohm ESR is compatible with the oscillator circuit's drive level requirements. Consider the -20°C to 70°C temperature range suitability for the intended operating environment.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series is characterized by small form factors suitable for space-constrained PCB layouts. The 402 series typically utilizes fundamental mode quartz resonators packaged in leadless SMD cases for reliable performance in consumer and industrial electronics.
