402F30711CDR

Crystals Overview

The CTS-Frequency Controls 402F30711CDR is a fundamental mode MHz crystal resonator designed for surface mount applications. It operates at a nominal frequency of 30.72 MHz with a frequency stability and tolerance of ±10 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 80 Ohms. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.00mm x 1.60mm and a maximum height of 0.55mm. The device supports operation within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Fundamental mode operation ensures precise timing synchronization
• Compact 4-SMD no-lead footprint suitable for space-constrained designs
• RoHS compliant construction supporting environmental regulations

Crystals Applications

• Wireless infrastructure equipment
• Wireline core networking systems
• General purpose timing circuits requiring 30.72 MHz reference

Crystals Procurement Notes

Verify the specific suffix 'CDR' against official CTS documentation to confirm package type and tape/reel specifications. Confirm that the ±10 ppm stability meets system requirements. Check current availability status as distribution channels may list obsolete or discontinued stock. Ensure compatibility with existing PCB footprints matching the 2.00mm x 1.60mm outline.

Crystals Selection Notes

Select this component when a 30.72 MHz fundamental crystal with ±10 ppm stability is required. The 18 pF load capacitance must match the oscillator circuit design. Consider the 80 Ohm ESR limit for drive level sensitivity. The -20°C to +70°C operating range defines the thermal environment suitability. Compare against other 402 series variants if different frequencies or tolerances are needed.

Crystals Part Context

This part belongs to the CTS 402 series of surface mount crystals. The series provides standard timing solutions for various electronic applications. The 402F30711CDR specifically addresses the need for a 30.72 MHz reference signal in compact form factors. It shares mechanical dimensions with other members of the 402 family but differs in electrical parameters such as frequency and tolerance.

Crystals Replacement Considerations

Direct substitutes include parts from the same 402 series with identical electrical characteristics. Verify pinout and dimensional compatibility before substitution. Cross-reference with manufacturer-approved alternative part numbers to ensure functional equivalence.
