Crystals Procurement Notes

Verify the manufacturer designation matches Suzhou Hangjing Elec&Tech Co., Ltd. Confirm the part number suffix corresponds to the specified 12 MHz frequency, 30pF load capacitance, and HC-49/U package. Ensure that the frequency tolerance of ±20ppm meets the system requirements. Check for any specific handling instructions regarding electrostatic discharge during installation.

Crystals Selection Notes

Select this component when a 12 MHz fundamental mode crystal is required in an HC-49/U package. The 30pF load capacitance must match the oscillator circuit design. The ±20ppm tolerance is suitable for general timing applications where high precision is not critical. Verify that the 30 Ohm ESR is compatible with the driving circuit's power constraints.

Crystals Part Context

This component belongs to the family of quartz crystal resonators produced by Suzhou Hangjing Elec&Tech Co., Ltd. The company specializes in quartz frequency controlling units. The HC-49/U form factor is widely used in consumer electronics and industrial equipment for providing reference clocks. This specific model represents a standard commercial-grade crystal solution.

Crystals Replacement Considerations

Substitutes must maintain the 12 MHz frequency, 30pF load capacitance, and HC-49/U package dimensions. Equivalent parts from other manufacturers should offer similar ±20ppm tolerance and 30 Ohm ESR specifications. Verify compatibility with existing PCB footprints and oscillator circuit parameters before replacement.
