402F26012IJR

Crystals Overview

The CTS-Frequency Controls 402F26012IJR is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 26 MHz with a frequency stability and tolerance of ±10 ppm. The component features a load capacitance of 9 pF and an equivalent series resistance (ESR) of 100 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.00 mm x 1.60 mm and a maximum height of 0.55 mm. The device supports operation within a temperature range of -40°C to +85°C and is supplied in tape and reel packaging.

Crystals Feature Summary

• Fundamental mode quartz crystal resonator for precise timing applications
• Compact 4-SMD surface-mount package suitable for automated assembly
• High frequency stability of ±10 ppm ensuring reliable clock signals
• RoHS compliant construction meeting environmental standards

Crystals Applications

• Microcontroller clock sources
• Communication module timing circuits
• Digital signal processing systems
• Consumer electronic devices requiring stable oscillation

Crystals Procurement Notes

Verify the specific suffix 'IJR' corresponds to the tape and reel packaging configuration rather than bulk or other formats. Confirm that the 9 pF load capacitance matches the target circuit design requirements. Check current availability status as supply chain conditions may affect lead times. Ensure the operating temperature range meets the environmental specifications of the final application.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency with tight ±10 ppm stability is required. The 9 pF load capacitance must align with the oscillator circuit's input and output capacitance values. Consider the 100 Ohm ESR limit for drive level sensitivity. The small 2.00 x 1.60 mm footprint is ideal for space-constrained PCB layouts compared to larger through-hole alternatives.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and packages optimized for consumer electronics. The 402F26012IJR specifically targets applications needing high stability in a minimal footprint. It complements other variants in the lineup differing primarily in frequency, capacitance, and package size options.

Crystals Replacement Considerations

Direct substitutes include 402F2601XILR and 402F26012ILT from CTS-Frequency Controls. Verify that alternative parts maintain identical 26 MHz frequency, 9 pF load capacitance, and ±10 ppm stability. Ensure the replacement package matches the 4-SMD No Lead form factor for proper board compatibility.
