402F2711XIAT

Crystals Overview

The CTS-Frequency Controls 402F2711XIAT is a surface-mount quartz crystal resonator operating at a fundamental frequency of 27.12 MHz. It features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 100 Ohms. The unit exhibits a frequency tolerance and stability of ±10 ppm and ±15 ppm, respectively. Packaged in a compact 4-SMD, No Lead form factor measuring 2.00mm x 1.60mm with a maximum seated height of 0.55mm, it supports operation within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Fundamental mode oscillation for precise timing applications
• Compact 4-SMD surface mount package design
• High frequency stability with ±10 ppm tolerance

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Embedded system synchronization circuits

Crystals Procurement Notes

Verify the specific suffix configuration against official CTS documentation to ensure compatibility with required load capacitance and tolerance levels. Confirm that the 4-SMD package dimensions align with PCB footprint constraints. Check current availability status as supply chain conditions may affect lead times. Ensure RoHS compliance requirements are met for the target assembly process.

Crystals Selection Notes

Select this component when a 27.12 MHz reference with tight frequency stability is required. The 10 pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR for drive level sensitivity. The limited operating temperature range suits standard commercial environments rather than harsh industrial conditions.

Crystals Part Context

This part belongs to the CTS 402 series of miniature crystals. The series offers various frequencies and package options for space-constrained designs. The 402F2711XIAT specifically targets applications needing stable 27.12 MHz generation in small footprints.

Crystals Replacement Considerations

Direct substitutes require matching 27.12 MHz frequency, 10 pF load capacitance, and 4-SMD package. Verify ESR and tolerance specifications. Cross-reference with other manufacturers' 27.12 MHz SMD crystals if CTS supply is unavailable.
