Crystals Procurement Notes

Verify that the specific part number suffix matches the required load capacitance of 18pF and the commercial temperature range (-20°C to +70°C). Ensure the ordering documentation explicitly confirms the 25MHz frequency and ±10ppm tolerance specifications to avoid substitution errors with similar variants offering different electrical characteristics or extended temperature ratings.

Crystals Selection Notes

Select this component when designing circuits requiring a 25MHz reference with moderate precision for commercial-grade environments. The 18pF load capacitance aligns with common STM32 and RK series MCU internal oscillators, potentially eliminating external matching capacitor adjustments. Consider the ±10ppm total deviation against Ethernet PHY requirements if high-speed data integrity is critical.

Crystals Part Context

This model belongs to the RH100 series of surface-mount crystals designed specifically for microprocessor applications. The series offers various frequencies and封装 sizes, providing engineers with options for different PCB space constraints and timing accuracy needs within the commercial and industrial sectors.

Crystals Replacement Considerations

Direct substitutes must match the 25MHz frequency, 18pF load capacitance, and 60Ω ESR maximum. Verify package dimensions and pin compatibility before replacing with alternative brands to ensure seamless integration into existing SMT processes.
