402WF26012IKR

Crystals Overview

The CTS-Frequency Controls 402WF26012IKR is a surface-mount quartz crystal resonator operating at a fundamental frequency of 26 MHz. It features an 8 pF load capacitance and a maximum equivalent series resistance (ESR) of 80 Ohms. The component provides a frequency tolerance of ±10 ppm and a stability of ±20 ppm across an operating temperature range of -40°C to +85°C. It utilizes a 4-SMD, No Lead package with dimensions of 2.0 mm x 1.6 mm.

Crystals Feature Summary

• Surface mount design for automated assembly
• Fundamental mode operation for stable frequency generation
• Compliant with RoHS3 standards

Crystals Applications

• Internet of Things (IoT) devices
• Microcontroller clock sources
• Communication modules

Crystals Procurement Notes

Verify the specific suffix 'IKR' against official CTS documentation to confirm packaging and tape-and-reel specifications. Ensure the application circuit matches the 8 pF load capacitance requirement. Confirm that the ±10 ppm tolerance meets system timing requirements before procurement.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency is required in a compact 2.0mm x 1.6mm footprint. It is suitable for applications needing ±10 ppm initial accuracy and operation within -40°C to +85°C. Consider ESR limits if driving circuit constraints are tight.
