Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct frequency, tolerance, and packaging specifications. Confirm that the selected variant matches the required load capacitance and ESR limits for the target circuit design. Check current availability status as inventory levels may fluctuate. Ensure compliance with regional environmental regulations such as RoHS before finalizing procurement orders.

Crystals Selection Notes

Select this component when a small form factor and wide temperature range are critical for IoT or industrial applications. The 4pF load capacitance requires matching with the oscillator circuit's stray capacitance to achieve the specified ±10ppm tolerance. Consider the 80 Ohm ESR limit to ensure proper oscillation startup conditions within the host system's clock generator architecture.

Crystals Part Context

This part belongs to the 402W series of enhanced quartz crystals from CTS-Frequency Controls. The series is characterized by its miniaturized 4-SMD package and optimized performance for modern embedded systems. It complements other variants in the lineup that offer different frequencies and tolerance grades while maintaining consistent physical dimensions and mounting characteristics.

Crystals Replacement Considerations

Direct substitutes must match the 30MHz frequency, 4pF load capacitance, and 2.00x1.60mm package dimensions. Verify that alternative components support the same -40°C to +85°C operating range and meet the 80 Ohm ESR requirement. Cross-reference pin configurations and electrical parameters to ensure compatibility with existing PCB layouts and oscillator circuits.
