Crystals Procurement Notes

Verify the specific ESR value (80 Ohms vs 100 Ohms max) against the official CTS datasheet prior to integration, as distributor listings may vary slightly. Confirm that the 4pF load capacitance matches your circuit design requirements. Ensure the -40°C to +85°C industrial temperature range aligns with your environmental specifications. Check for RoHS3 compliance status if required by your manufacturing standards.

Crystals Selection Notes

Select this component when a 24.576 MHz reference is needed for Wi-Fi or Bluetooth low energy protocols due to its mathematical compatibility with common baud rates. The 4pF load capacitance requires careful PCB trace impedance matching. Consider the small 2x1.6mm package size for space-constrained designs. Verify that the ±10ppm tolerance meets the system's jitter budget compared to standard ±20ppm alternatives.

Crystals Part Context

This part belongs to the CTS 402W series, which focuses on enhanced performance for wireless and IoT markets. It differs from the standard 402 series by offering tighter tolerances and optimized characteristics for modern low-power networking chips. The 'IMR' suffix typically indicates the tape and reel packaging format for automated assembly.

Crystals Replacement Considerations

Direct substitutes include other 24.576 MHz crystals with 4pF load capacitance and similar 2.0x1.6mm footprints. Verify ESR limits and temperature ranges carefully. Generic replacements may lack the specific IoT optimization claims. Cross-reference with CTS part numbers like 402F24C12IMR if looser tolerances are acceptable.
