• High frequency stability with ±10 ppm initial tolerance
• Low aging rate of 3 ppm per year for long-term reliability
• RoHS compliant and lead-free construction

Crystals Applications

• General-purpose clock generation circuits
• Microcontroller system timing references
• Communication equipment frequency standards
• Consumer electronics internal clocks

Crystals Procurement Notes

Verify the specific suffix 'R' against the manufacturer's current datasheet to confirm packaging details and availability status. Ensure that the 18 pF load capacitance matches the target circuit design requirements. Confirm RoHS compliance documentation is available for regulatory adherence. Cross-reference the 30 Ohm ESR value with oscillator driver strength specifications to prevent overdriving or failure to oscillate during integration.

Crystals Selection Notes

Select this component when a 16 MHz surface-mount solution with high precision is required. The 18 pF load capacitance must align with the host oscillator circuit's capacitive load. Consider the 5032 package size for PCB space constraints. The ±10 ppm tolerance suits applications demanding tighter frequency accuracy than standard ±20 or ±30 ppm parts. Verify the 100 µW drive level compatibility with the specific microcontroller or logic family being utilized.

Crystals Part Context

This part belongs to the C5S series of surface-mount crystals from Aker Technology Corp. The series offers various frequencies and packages, including the 5032 form factor shown here. It serves as a passive frequency control element, distinct from active oscillators which include built-in circuitry. The C5S line targets general electronic applications requiring reliable timing sources without automotive qualification.

Crystals Replacement Considerations

Direct substitutes may include other 16 MHz SMD crystals with 18 pF load and similar dimensions. Check for identical pinout configurations in 4-pin SMD packages. Verify that alternative parts meet the same ±10 ppm tolerance and 30 Ohm ESR specifications. Ensure replacement components support the -40°C to +85°C operating temperature range.
