403C11B26M00000

Crystals Overview

The CTS-Frequency Controls 403C11B26M00000 is a surface-mount quartz crystal resonator operating at a fundamental frequency of 26 MHz. It features a load capacitance of 13 pF and an equivalent series resistance (ESR) of 60 Ohms. The component offers a frequency tolerance of ±10 ppm and stability of ±30 ppm. Designed for the -20°C to +70°C temperature range, it utilizes a 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm x 0.85mm maximum height.

Crystals Feature Summary

• Fundamental mode operation for precise timing applications
• High frequency tolerance of ±10 ppm ensures signal accuracy
• Compact 4-SMD no-lead footprint suitable for automated assembly

Crystals Applications

• Microcontroller clock sources
• Communication interface circuits
• Embedded system timing references

Crystals Procurement Notes

Verify the specific suffix 'B' indicates the required ±10 ppm tolerance against design requirements. Confirm the 13 pF load capacitance matches the oscillator circuit's external capacitor values. Ensure the 60 Ohm ESR is compatible with the driving circuit's power limits to prevent overdriving the crystal.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency is required with tight initial tolerance. Compare the 60 Ohm ESR against lower-resistance alternatives if drive level sensitivity is a concern. Evaluate the 3.20x2.50mm package size against board space constraints relative to larger 5x3.2mm variants in the same series.

Crystals Part Context

This part belongs to the 403 series of SMD crystals from CTS-Frequency Controls. It shares the 3.20x2.50mm form factor with other members like the 403C35D32M00000 but differs in frequency and tolerance specifications. The series provides standard surface-mount solutions for general-purpose timing needs.

Crystals Replacement Considerations

Direct substitutes include the 403I35B26M00000 from the same manufacturer. Verify that any alternative maintains the identical 13 pF load capacitance and 60 Ohm ESR to ensure circuit compatibility without redesign.
