405C35S27M00000

Crystals Overview

The CTS-Frequency Controls part number 405C35S27M00000 is a fundamental mode MHz crystal designed for surface mount applications. It operates at a nominal frequency of 27 MHz with a load capacitance specified as series and an equivalent series resistance (ESR) of 50 Ohms. The component exhibits a frequency stability of ±50ppm and a frequency tolerance of ±30ppm. It is housed in a 4-SMD, No Lead package with dimensions of 5.00mm x 3.20mm and a maximum height of 0.85mm. The device supports an operating temperature range of -20°C to +70°C and complies with RoHS3 standards.

Crystals Feature Summary

• Fundamental mode operation ensures stable oscillation characteristics.
• Surface mount design facilitates automated assembly processes.
• Compliant with RoHS3 environmental regulations.

Crystals Applications

• General purpose clock signal generation
• Microcontroller timing circuits
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as the datasheet lists this parameter as 'Series' rather than a fixed value. Confirm that the standard 23-week lead time aligns with project schedules. Ensure the -20°C to +70°C operating range meets the environmental constraints of the final application before procurement.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal is required for space-constrained designs. The 4-SMD footprint offers a compact solution compared to through-hole alternatives. Consider the ±30ppm tolerance if higher precision is needed, or evaluate industrial grade variants for extended temperature requirements beyond the commercial range.

Crystals Part Context

This component belongs to the CTS 405 Series, which provides a range of surface mount crystals. The 'S' designation typically indicates a series resonant configuration. This specific model shares physical dimensions and mounting characteristics with other frequencies in the series, allowing for potential footprint reuse across different design iterations within the same product family.
