402F26022IJT

Crystals Overview

The CTS-Frequency Controls 402F26022IJT is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 26 MHz with a frequency tolerance and stability of ±20 ppm. The component features a load capacitance of 9 pF and an equivalent series resistance (ESR) of 100 Ohms. It utilizes a hermetic ceramic package in a 4-SMD, no-lead configuration with dimensions of 2.00 mm x 1.60 mm x 0.55 mm. The device supports operation within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Crystals Feature Summary

• Fundamental oscillation mode ensures stable frequency generation
• Hermetic ceramic construction provides environmental protection
• Sub-miniature surface-mount footprint facilitates automated assembly

Crystals Applications

• Clock signal generation for microprocessors
• Frequency reference for communication modules
• Timing circuits in consumer electronics

Crystals Procurement Notes

Verify the specific suffix 'IJT' against official CTS documentation to confirm tape-and-reel packaging and lead-free termination specifications. Cross-reference the 9pF load capacitance requirement with circuit design parameters to ensure impedance matching. Confirm that the 100 Ohm ESR aligns with oscillator driver strength limitations. Validate compliance with current RoHS3 directives before final procurement approval.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency with ±20 ppm stability is required in a compact SMD form factor. Ensure the application circuit can accommodate a 9pF load capacitance and 100 Ohm ESR. Verify that the operating temperature range of -40°C to +85°C meets environmental requirements. Consider the hermetic package for reliability in harsh conditions compared to non-hermetic alternatives.

Crystals Part Context

This part belongs to the CTS 402 Series, which offers sub-miniature surface-mount crystals. The series typically covers frequencies from 16 MHz to 96 MHz in a 2.0 x 1.6 mm package. The 402F26022IJT represents a specific frequency code within this standardized family, sharing common mechanical and electrical characteristics with other variants in the lineup.

Crystals Replacement Considerations

Direct substitutes include 402F26022IAR and 402F26022ILR from CTS-Frequency Controls. These parts share identical electrical specifications but may differ in packaging or suffix codes. Verify pin compatibility and parameter equivalence before substitution.
