Crystals Procurement Notes

Verify the specific suffix 'ILR' matches the required load capacitance and tolerance specifications for your circuit design. Confirm that the 4-SMD footprint dimensions align with your PCB layout constraints. Ensure compatibility with standard reflow soldering profiles suitable for leadless surface mount components. Check current availability status as supply levels may fluctuate.

Crystals Selection Notes

Select this component when a 48 MHz fundamental frequency with tight ±10 ppm tolerance is required. The 12 pF load capacitance must match the oscillator circuit's external capacitors. Consider the 60 Ohm ESR limit for drive level sensitivity. The compact 1.60mm x 1.20mm size is suitable for space-constrained designs requiring reliable timing accuracy.

Crystals Part Context

This part belongs to the CTS 402 series of miniature crystals. It shares similar packaging and electrical characteristics with other variants in the series but differs in frequency and tolerance specifications. The 402 series is designed for high-volume surface mount applications requiring consistent performance.

Crystals Replacement Considerations

Direct substitutes include parts with identical 48 MHz frequency, 12 pF load capacitance, and ±10 ppm tolerance in a 4-SMD package. Verify ESR values and temperature ranges before substitution. Cross-reference with manufacturer-approved equivalents to ensure pin-out and mechanical compatibility.
