403C11A26M00000

Crystals Overview

The CTS-Frequency Controls 403C11A26M00000 is a fundamental AT-cut crystal resonator operating at a nominal frequency of 26 MHz. It features a frequency stability and tolerance of ±10 ppm at +25°C, with a standard tolerance of ±30 ppm across the temperature range. The component utilizes a load capacitance of 10 pF and an equivalent series resistance (ESR) of 60 Ohms maximum. Designed for surface-mount applications, it is housed in a compact 4-SMD, No Lead package with dimensions of 3.2 mm x 2.5 mm. The device supports a functional temperature range from -20°C to +70°C and complies with RoHS3 standards.

Crystals Procurement Notes

Verify that the specific order matches the 403C11A26M00000 designation to ensure correct 26 MHz frequency and 10 pF load capacitance. Confirm package compatibility with the 3.2mm x 2.5mm footprint. Check datasheet for soldering profile recommendations to maintain integrity during reflow processes. Ensure storage conditions prevent moisture damage prior to use.

Crystals Selection Notes

Select this component when a 26 MHz fundamental mode crystal is required with tight ±10 ppm stability. The 10 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR limit for driver strength requirements. The -20°C to +70°C range suits general commercial applications rather than extreme industrial environments.

Crystals Part Context

This part belongs to the CTS 403 Series of surface-mount crystals. The series offers various frequencies within the 8–80 MHz range. The 403C11A26M00000 specifically targets applications needing high stability in a small form factor. It serves as a core timing element in modern electronic systems where space constraints and performance reliability are critical design factors.

Crystals Replacement Considerations

Direct substitutes include other 26 MHz crystals with identical 10 pF load capacitance and ±10 ppm stability. Verify ESR limits do not exceed 60 Ohms. Ensure replacement parts support the same 4-SMD No Lead package dimensions. Cross-reference with manufacturer cross-listings for equivalent components.
