Crystals Procurement Notes

Verify the specific load capacitance requirements against your circuit design to ensure accurate oscillation frequency. Confirm that the PCB land pattern matches the 4-SMD no-lead package dimensions provided in the official datasheet. Ensure storage conditions comply with manufacturer guidelines to maintain component integrity prior to soldering.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required with moderate frequency stability. The 8pF load capacitance must match the external circuit parameters. Consider the ±25ppm tolerance limit for temperature and aging effects in your system design. Verify compatibility with standard reflow soldering profiles for lead-free assembly.

Crystals Part Context

This part belongs to Suntsu Electronics' family of ceramic surface-mount crystals. These components are engineered for compact electronic designs requiring precise frequency control. The 4-SMD form factor allows for high-density mounting on printed circuit boards, supporting modern miniaturization trends in consumer and industrial electronics.

Crystals Replacement Considerations

Cross-reference compatible parts from other manufacturers offering identical 40 MHz frequency, 8pF load capacitance, and 4-SMD package dimensions. Ensure substitute components meet or exceed the original ±25ppm tolerance and 60 Ohms maximum resistance specifications to maintain system performance.
