402F26011CAT

Crystals Overview

The 402F26011CAT is a MHz crystal manufactured by CTS-Frequency Controls. It operates at a nominal frequency of 26 MHz with a frequency stability of ±10ppm and a load capacitance of 10pF. The component features an equivalent series resistance (ESR) of 100 Ohms and utilizes a base harmonic operating mode. It is housed in a compact 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm and a maximum height of 0.45mm. Designed for surface mount installation, it supports a commercial operating temperature range of -20°C to +70°C.

Crystals Feature Summary

• Provides precise timing signals through stable oscillation at 26 MHz.
• Utilizes a low-profile surface mount package for automated assembly integration.
• Ensures reliable performance within standard commercial temperature environments.

Crystals Applications

• Precision timing circuits requiring stable clock references
• Microcontroller system clock generation
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific suffix CAT against the manufacturer's current documentation to confirm package and tape specifications. Confirm that the ±10ppm stability meets the target application requirements. Check for RoHS3 compliance status if environmental regulations apply. Ensure the 10pF load capacitance matches the oscillator circuit design parameters before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 26 MHz frequency is required with tight ±10ppm stability. The 100 Ohm ESR value must align with the driving circuit capabilities. Consider the 4-SMD footprint for space-constrained designs. Verify that the commercial temperature range suffices for the intended operational environment compared to industrial alternatives.
