Crystals Feature Summary

• High frequency stability with ±10 ppm tolerance for precise clock generation
• Compact 4-SMD surface-mount package optimized for space-constrained PCB layouts
• Industrial temperature rating supporting operation from -40°C to +85°C
• Fundamental mode operation with low equivalent series resistance

Crystals Applications

• Microcontroller clock sources requiring stable timing references
• Communication interfaces such as UART and SPI bus synchronization
• Digital signal processing circuits needing accurate sampling rates
• Embedded systems with strict frequency accuracy requirements

Crystals Procurement Notes

Verify the specific suffix 'A' indicates the 10pF load capacitance variant distinct from standard 20pF or 30pF options. Confirm that the ±10ppm tolerance meets system jitter budgets. Ensure the 4-SMD footprint matches the design layout dimensions of 3.20mm x 2.50mm. Check for RoHS compliance documentation if required by regulatory standards. Validate supply chain availability through authorized distributors due to potential lead times.

Crystals Selection Notes

Select this component when a 24.576 MHz reference is needed with tighter stability than standard ±30ppm crystals. The 10pF load capacitance requires matching circuit capacitors to achieve resonance. Consider the 60 Ohm ESR for oscillator drive level calculations to prevent over-driving. The industrial temperature range makes it suitable for harsher environments compared to commercial grade parts. Ensure the mounting pad design accommodates the no-lead SMD structure.
