Procurement Notes

Verify the specific suffix 'IST' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the design accommodates the 60 Ohm ESR limit and 50 MHz load requirements. Confirm that the -40°C to +85°C operating range aligns with the target application environment. Check for any recent lifecycle status changes or obsolescence notices from CTS-Frequency Controls before finalizing procurement plans.

Selection Notes

Select this component when a 50 MHz fundamental frequency with ±20 ppm stability is required in a compact SMD form factor. The 60 Ohm ESR specification must match the oscillator circuit design to ensure reliable startup. Consider the industrial temperature range if the application operates in harsh environments. Verify that the 4-SMD no-lead package fits within the available PCB real estate constraints.
