Crystals Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's official datasheet to ensure compatibility with your PCB footprint. Confirm that the required operating temperature range of -20°C to +70°C meets your application's environmental specifications. Cross-reference the load capacitance requirement of 18 pF with your circuit design to maintain accurate frequency performance. Ensure compliance with RoHS directives if applicable to your manufacturing region.

Crystals Selection Notes

Select this component when a precise 48 MHz timing source is required in space-constrained designs. The 18 pF load capacitance must match the external circuit requirements to achieve the specified ±30 ppm stability. Consider the 60 ohm ESR value for oscillator circuit design to ensure reliable startup. The SMD2016-4P package is suitable for automated assembly processes requiring small form factors.

Crystals Part Context

This part belongs to the SXT series of surface-mount crystals from Suntsu Electronics, Inc. The series offers various frequencies and packages tailored for modern electronic devices. The SXT21418BA27-48.000M specifically utilizes a 4-pin SMD configuration, distinguishing it from older leaded or different pin-count variants within the broader product line.

Crystals Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 18 pF load capacitance, and 4-SMD No Lead package dimensions. Verify that alternative components support the same ±30 ppm stability and 60 ohm ESR specifications. Ensure the replacement part also accommodates the -20°C to +70°C operating temperature range. Check for identical mounting pad layouts to facilitate drop-in replacement without PCB redesign.
