Crystals Procurement Notes

Verify the specific suffix 'A' and '-TR' against the manufacturer's current datasheet to confirm package dimensions and tape & reel specifications. Ensure the load capacitance requirement matches the target circuit design before procurement. Confirm that the ±20 ppm tolerance meets the application's timing accuracy requirements.

Crystals Selection Notes

Select this component when a low-cost, surface-mount tuning fork crystal is required for 32.768 kHz applications. The 50 kOhms ESR suits high-impedance oscillator circuits. Compare physical dimensions against PCB space constraints. Verify compatibility with reflow soldering profiles for plastic packages.
