Crystals Procurement Notes

Verify the specific package dimensions and pin configuration against the official datasheet before integration. Confirm that the load capacitance requirements of the host circuit align with the 8pF specification. Ensure the operating temperature range meets the environmental demands of the final application. Cross-reference the part number with authorized distributors to guarantee authenticity and traceability.

Crystals Selection Notes

Select this model when a small footprint is critical alongside moderate frequency stability. The 20MHz frequency suits many microcontroller and communication interfaces. Consider the 150 Ohm ESR value for oscillator circuit design compatibility. Evaluate the ±20ppm tolerance against system timing requirements to ensure adequate margin for long-term drift and temperature variations.

Crystals Part Context

This component belongs to the SAX214 series from Suntsu Electronics, which specializes in high-reliability ceramic crystals.
