Crystals Procurement Notes

Verify the specific load capacitance requirements of the target circuit against the 32 pF specification of this component. Confirm that the operating temperature range aligns with the environmental conditions of the final assembly. Ensure the HC-49/US package dimensions fit within the designated mechanical constraints of the printed circuit board layout.

Crystals Selection Notes

Select this part when a 20 MHz reference signal is required for through-hole implementations. Consider the 30 Ohm series resistance regarding drive level limitations. Evaluate the ±50 ppm stability against system timing accuracy needs. Compare the physical dimensions of the HC-49/US case against available board space.

Crystals Part Context

This component belongs to the standard crystal unit category from TXC Corporation. It serves as a passive frequency-determining element within oscillator circuits.
