• Wireless communication devices

Crystals Procurement Notes

Verify the specific suffix configuration against the official Abracon datasheet to ensure alignment with required load capacitance and tolerance specifications. Confirm that the HC/49US package dimensions match the target PCB footprint requirements. Ensure compliance with RoHS directives if the application demands lead-free assembly standards. Cross-reference the part number with the manufacturer's current inventory status to avoid discrepancies in ordering suffixes.

Crystals Selection Notes

Select this component when a standard 3.579545 MHz reference is required for microprocessor or modem circuits. The 18 pF load capacitance must match the oscillator circuit design parameters. Consider the low profile height for space-constrained layouts. Verify that the ±20 ppm initial tolerance meets the system timing accuracy requirements. Ensure the operating temperature range aligns with the environmental conditions of the final application.

Crystals Part Context

This part belongs to the ABLS series of low-profile surface mount crystals from Abracon. It shares the HC/49US form factor with other variants in the lineup but differs in electrical parameters such as tolerance and load capacitance based on its specific suffix. The series is engineered for high-volume consumer electronics where size and cost efficiency are critical factors.

Crystals Replacement Considerations

Direct substitutes include other Abracon ABLS series parts with identical 3.579545 MHz frequency and 18 pF load capacitance. Verify that alternative parts maintain the same ±20 ppm tolerance and 180 Ω ESR to ensure circuit compatibility without redesign.
