Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design before procurement. Confirm that the ±10 ppm frequency tolerance meets the system's timing accuracy specifications. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the 4-SMD footprint dimensions with the PCB layout to guarantee proper solder joint formation and mechanical reliability during assembly processes.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required with a 9 pF load capacitance. The ±10 ppm stability suits applications requiring moderate precision. Consider the 100 Ohm ESR value for oscillator circuit loading calculations. The -20°C to +70°C range defines the operational limits. Compare against other 402 series variants if different capacitances or tolerances are needed.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and load capacitances in a compact 2.0mm x 1.6mm package. These components are designed for general-purpose timing applications where space constraints exist. The 402 series provides a balance between performance and size for consumer and industrial electronics.

Crystals Replacement Considerations

Substitutes must match the 27 MHz frequency, 9 pF load capacitance, and 4-SMD package. Verify ESR and stability tolerance compatibility. Check datasheets for pinout and dimensional equivalence.
