Crystals Procurement Notes

Verify the specific suffix 'LR' corresponds to tape-and-reel packaging when sourcing. Confirm that the 12pF load capacitance matches the target circuit design requirements. Ensure the -40°C to +85°C temperature range aligns with the operational environment. Cross-reference the 100 Ohm ESR value with oscillator driver strength specifications to prevent over-driving.

Crystals Selection Notes

Select this component for designs requiring a 27.12 MHz reference signal in space-constrained PCB layouts. The 4-SMD footprint allows for automated assembly processes. Consider the ±10 ppm tolerance for applications needing precise timing synchronization. Evaluate the 12pF load capacitance against the host oscillator's internal capacitance settings.

Crystals Part Context

This part belongs to the CTS 402 Series, which offers sub-miniature surface-mount crystals. The series provides various frequencies within the 16–96 MHz range using AT-cut quartz technology. The 402F2711XILR specifically addresses the need for reliable timing in portable and industrial electronics where small form factors are critical.

Crystals Replacement Considerations

Publicly documented parameter-equivalent substitutes include 402F2711XIAR and 402F2711XIJR from CTS-Frequency Controls. These alternatives share identical electrical characteristics and physical dimensions, allowing for direct pin-compatible replacement in existing designs.
