• Microcontroller oscillator circuits
• Communication interface timing references

Crystals Procurement Notes

Verify the specific suffix 'B' indicates the 13pF load capacitance variant, as other suffixes like 'D' may denote different electrical parameters such as 18pF. Confirm the 50 Ohm ESR requirement matches the target circuit design. Ensure the -20°C to +70°C commercial temperature range meets application thermal constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency crystal is required in a compact 5.00x3.20mm footprint. The 13pF load capacitance must align with the host oscillator's specified load requirements. Consider the 50 Ohm ESR limit for drive level sensitivity. This part is suitable for standard commercial applications where the specified temperature range is sufficient.

Crystals Part Context

This component belongs to the 405 Series of SMD crystals from CTS-Frequency Controls. The series provides various frequencies and packages, with the 405C35B27M00000 representing a specific 27 MHz configuration. It shares the general form factor and manufacturing technology with other members of the 405 family, differing primarily in frequency and load capacitance specifications.

Crystals Replacement Considerations

Direct substitutes within the same manufacturer series include variants with different load capacitances or tolerances, such as 405C35D27M00000. Cross-manufacturer replacements require matching the 27 MHz frequency, 13pF load capacitance, 50 Ohm ESR, and 4-SMD 5.00x3.20mm package dimensions to ensure compatibility.
