402F26011CKR

Crystals Overview

The CTS-Frequency Controls 402F26011CKR is a surface-mount quartz crystal resonator operating at a fundamental frequency of 26 MHz. It features a frequency stability and tolerance of ±10 ppm, with an equivalent series resistance (ESR) of 100 Ohms maximum. The component is designed for a load capacitance of 8 pF and utilizes a 4-SMD, no-lead package measuring 2.00 mm x 1.60 mm in footprint with a maximum height of 0.55 mm. It supports a commercial operating temperature range from -20°C to +70°C.

Crystals Feature Summary

• Fundamental mode operation for precise frequency generation
• Compact 4-SMD no-lead surface mount packaging
• RoHS3 compliant construction without lead content

Crystals Applications

• Microcontroller clock source circuits
• Communication module timing references
• Digital signal processing interfaces

Crystals Procurement Notes

Verify the specific suffix CKR against official datasheets to confirm tape-and-reel packaging requirements. Confirm that the 8 pF load capacitance matches the target circuit design. Check current availability status as distribution channels may list discontinued or limited stock variants. Ensure EDA models align with the physical dimensions provided.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency with ±10 ppm stability is required. The 100 Ohm ESR must be compatible with the oscillator circuit's drive level constraints. Verify that the 8 pF load capacitance matches the system design. The commercial temperature range suits standard electronic equipment applications.

Crystals Part Context

This part belongs to the CTS 402 Series of miniature surface-mount crystals. The series offers various frequencies and package sizes optimized for space-constrained designs. The 402F26011CKR specifically provides a 26 MHz output in a 2.00x1.60 mm footprint, balancing performance with compactness.

Crystals Replacement Considerations
