Crystals Procurement Notes

Verify the specific ESR requirement against your circuit design, as datasheet variations exist within the 402 series. Confirm that the 18pF load capacitance matches your oscillator circuit's total stray capacitance. Ensure the operating temperature range of -20°C to +70°C meets your application's environmental constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a 20 MHz fundamental mode crystal is required in a small surface-mount footprint. The 18pF load capacitance is standard for many CMOS oscillator circuits. Consider the ±10 ppm initial tolerance if higher precision is not critical. Verify compatibility with your PCB layout guidelines for 4-SMD packages.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals, which are widely used in consumer electronics and industrial equipment. The series offers various frequencies and package sizes, providing designers with flexible options for integrating quartz timing elements into space-constrained printed circuit boards without compromising performance or reliability.

Crystals Replacement Considerations

Direct substitutes within the same series include other 402F200XX variants with different tolerances or ESR values. Cross-reference the 402F20011CDR variant if leaded packaging is acceptable, though pinout and mechanical dimensions differ. Always verify electrical parameters match exactly when substituting.
