435F27135CDT

Crystals Overview

The CTS-Frequency Controls 435F27135CDT is a surface-mount quartz crystal resonator operating at a fundamental frequency of 27.12 MHz. It features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 40 Ohms. The component provides a frequency tolerance of ±15 ppm and a stability of ±30 ppm over the specified temperature range. Designed for compact electronics, it utilizes a 2-SMD, no-lead package with dimensions of 2.5 mm x 2.0 mm x 0.6 mm.

Crystals Feature Summary

• Fundamental mode operation ensures precise timing synchronization for digital circuits.
• Low ESR value supports efficient circuit design and stable oscillation.
• Compact surface-mount footprint facilitates automated assembly in space-constrained PCB layouts.

Crystals Applications

• Embedded communication modules requiring precise clock signals
• Wireless infrastructure equipment
• Wireline core networking devices

Crystals Procurement Notes

Verify the specific suffix 'CDT' against official CTS documentation to confirm tape-and-reel packaging and lead-free status. Ensure the selected variant matches the required 18pF load capacitance and 40 Ohm ESR specifications for your oscillator circuit design before finalizing procurement.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental crystal with tight ±15 ppm tolerance is required. The 18pF load capacitance must match the host circuit's external capacitor values. Consider the 2-SMD package size constraints and the -40°C to +85°C industrial temperature range suitability for the target application environment.

Crystals Part Context

This part belongs to the 435 series of SMD crystals from CTS-Frequency Controls. The series is characterized by small form factors and high reliability, targeting modern consumer and industrial electronics. It complements other frequency control products like the 416 series, offering different package sizes and electrical characteristics for diverse design needs.

Crystals Replacement Considerations

Direct substitutes include parts with identical 27.12 MHz frequency, 18pF load capacitance, and 40 Ohm ESR in a 2-SMD package. Verify that any replacement maintains the same ±15 ppm tolerance and industrial temperature rating to ensure circuit compatibility without redesign.
