It operates within a temperature range of -40°C to +85°C and maintains a frequency stability of ±50ppm. The component features an 18pF load capacitance and utilizes the HC-49/US package style. This surface-mount device is designed for applications requiring precise timing signals with specific environmental tolerance and electrical characteristics.

Crystals Feature Summary

• Fundamental oscillation mode operation
• Wide industrial temperature range capability
• Standardized surface-mount form factor

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• Digital signal processing circuits

Crystals Procurement Notes

Verify the exact frequency tolerance specification against the official datasheet, as conflicting data exists regarding ±50ppm versus ±25ppm ratings. Confirm the physical package dimensions match the required PCB layout constraints. Ensure the supplier provides valid RoHS compliance documentation. Cross-reference the manufacturer part number directly with Suntsu Electronics to avoid counterfeit components.

Crystals Selection Notes

Select this component when a 30 MHz reference is required for fundamental mode crystals. Consider the ±50ppm stability requirement relative to system timing budgets. Evaluate the HC-49/US package compatibility with automated assembly processes. Compare thermal performance against the specified -40°C to +85°C operational limits for the target environment.

Crystals Part Context

This model belongs to the SXTHM series of crystal resonators from Suntsu Electronics. It shares design principles with other variants in the line but differs in frequency, tolerance, and package specifics. The series targets general-purpose timing applications requiring reliable fundamental mode operation.

Crystals Replacement Considerations

Direct substitutes must match the 30 MHz frequency, 18pF load capacitance, and HC-49/US package. Verify equivalent frequency stability and temperature range specifications before integration.
