Crystals Procurement Notes

Verify the manufacturer designation carefully, as the model number appears associated with both FTS and TXC Corporation across different distributors. Confirm the package type matches your PCB footprint requirements, as HC-49/US can vary between through-hole and surface-mount styles. Check lifecycle status, as some sources list this part as obsolete while others indicate active availability. Ensure the datasheet confirms the specific electrical parameters required for your circuit design before ordering.

Crystals Selection Notes

Select this component when a 20 MHz reference signal is needed with ±30ppm initial accuracy. The 12pF load capacitance must match the oscillator circuit design to ensure frequency accuracy. Consider the operating temperature range specified in the official datasheet to ensure performance within your application environment. Verify that the ESR value of 50 Ohms is compatible with your oscillator driver strength.

Crystals Part Context
