403I35E27M00000

Crystals Overview

The CTS-Frequency Controls 403I35E27M00000 is a surface-mount quartz crystal resonator operating at a fundamental frequency of 27 MHz. It features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 60 Ohms. The component exhibits a frequency tolerance of ±30 ppm and stability of ±50 ppm. Designed for industrial applications, it supports a temperature range of -40°C to +85°C. The device utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.030 inches (0.75mm).

Crystals Feature Summary

• Fundamental mode operation ensures precise frequency generation.
• Industrial-grade temperature range supports harsh environments.
• Compact surface-mount footprint facilitates automated assembly.

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• Industrial control systems

Crystals Procurement Notes

Verify the specific suffix 'I' indicates the extended industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm that the 20pF load capacitance matches the oscillator circuit design requirements. Ensure the 4-SMD no-lead package dimensions align with the PCB land pattern specifications to prevent soldering defects during reflow processes.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required with tight ±30 ppm tolerance. The 60 Ohm ESR must be compatible with the driving circuit's oscillation conditions. Consider the 4-SMD package size if space constraints exist within the target application board layout relative to larger through-hole alternatives.

Crystals Part Context

This part belongs to the CTS 403 Series of surface-mount crystals. The series offers various frequencies in standardized small footprints. The 'I' designation typically denotes industrial temperature rating, distinguishing it from commercial grade options within the same physical package family.

Crystals Replacement Considerations
