Crystals Procurement Notes

Verify RoHS compliance status and lead-free certification directly with the manufacturer or authorized distributors before procurement. Confirm that the HC-49/US package dimensions align with your PCB footprint requirements. Ensure thermal profiles during soldering adhere to recommended specifications to maintain frequency stability and prevent mechanical stress on the crystal element.

Crystals Selection Notes

Select this component when a through-hole solution is required for 12 MHz applications. Compare the 20 pF load capacitance against circuit design requirements to ensure proper oscillator loading. Consider the 40 Ohm series resistance impact on start-up time. Evaluate the HC-49/US package size constraints relative to available board space compared to surface-mount alternatives.

Crystals Part Context

This part belongs to the general quartz crystal resonator category within TXC's portfolio. It serves as a passive frequency-determining element for electronic circuits. The HC-49/US form factor represents a legacy but widely adopted standard for through-hole implementations. It differs from surface-mount crystals like the 7B series by offering higher mechanical robustness and easier manual handling.
