402F27012ILT

Crystals Overview

The CTS-Frequency Controls 402F27012ILT is a surface-mount MHz crystal operating at 27.0000 MHz with a load capacitance of 12pF. It features a frequency stability and tolerance of ±10ppm, an equivalent series resistance (ESR) of 100 Ohms, and operates in fundamental mode. The component is housed in a 4-SMD, No Lead package measuring 2.00mm x 1.60mm x 0.55mm maximum height. It supports an operating temperature range of -40°C to +85°C and complies with RoHS3 standards.

Crystals Feature Summary

• Provides precise timing signals for digital circuits using quartz resonance technology.
• Designed for compact surface-mount assembly on printed circuit boards.
• Ensures stable frequency output across specified industrial temperature ranges.

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• Digital signal processing systems

Crystals Procurement Notes

Verify the specific suffix 'ILT' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the ±10ppm frequency tolerance meets the system's jitter and phase noise requirements. Ensure the 12pF load capacitance matches the oscillator circuit design specifications provided by the host controller manufacturer.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal is required with tight ±10ppm stability. Compare against the 402F27012IDT variant if different packaging or ESR characteristics are needed. Evaluate the 4-SMD footprint dimensions against available PCB real estate constraints. Consider the -40°C to +85°C range suitability for the intended environmental conditions.
