403C35D27M00000

Crystals Overview

The CTS-Frequency Controls 403C35D27M00000 is a surface-mount quartz crystal resonator operating at a fundamental frequency of 27 MHz. It features a load capacitance of 18 pF and a frequency tolerance of ±30 ppm, with a stability of ±50 ppm. The component has an equivalent series resistance (ESR) of 60 Ohms and operates within a temperature range of -20°C to +70°C. It is housed in a compact 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a maximum height of 0.030 inches (0.75 mm).

Crystals Feature Summary

• Fundamental mode operation for precise frequency control.
• Compact 4-SMD no-lead surface mount design.
• RoHS3 compliant construction.

Crystals Applications

• General-purpose clock signal generation.

Crystals Procurement Notes

Verify the specific package dimensions and ESR against the official datasheet before integration. Confirm that the 18 pF load capacitance matches the oscillator circuit requirements. Ensure the operating temperature range meets the application environment. Check for RoHS3 compliance if required by project specifications.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required in a small footprint. Consider the 60 Ohm ESR and 18 pF load capacitance for circuit compatibility. Evaluate the ±30 ppm tolerance against system accuracy needs. Compare physical size constraints with alternative packages.

Crystals Part Context

This part belongs to the 403 series of SMD crystals from CTS-Frequency Controls. It shares the 27 MHz frequency with other variants but differs in package style and electrical parameters. The 403 series offers various load capacitances and tolerances for different oscillator designs.

Crystals Replacement Considerations

Direct substitutes include parts with identical 27 MHz frequency, 18 pF load capacitance, and compatible ESR values. Verify pinout compatibility for 4-SMD packages. Cross-reference manufacturer datasheets for mechanical and electrical equivalence.
