402F50022ILR

Crystals Overview

The CTS-Frequency Controls 402F50022ILR is a 50 MHz fundamental mode crystal resonator designed for surface-mount applications. It features a frequency tolerance of ±20ppm at normal temperature and an equivalent series resistance (ESR) of 60 Ohms maximum. The component operates with a load capacitance of 12pF and supports an extended operating temperature range from -40°C to +85°C. It utilizes a compact 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm and a maximum height of 0.45mm.

Crystals Feature Summary

• Fundamental mode operation ensures stable frequency generation
• Extended temperature range suitable for harsh environments
• Compact leadless surface-mount design for space-constrained PCBs

Crystals Applications

• High-frequency clock signal generation in digital circuits
• Timing reference sources for microcontrollers and processors
• Communication equipment requiring precise frequency stability

Crystals Procurement Notes

Verify the specific suffix 'ILR' against official CTS documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure the load capacitance requirement matches the circuit design. Confirm RoHS compliance status through current manufacturer declarations rather than assuming historical data.

Crystals Selection Notes

Select this component when a 50 MHz fundamental crystal with ±20ppm initial tolerance is required. The 12pF load capacitance must align with the oscillator circuit's stray capacitance. Consider the -40°C to +85°C range if the application involves variable thermal conditions. The low ESR of 60 Ohms supports efficient drive levels.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. It shares the same physical footprint and general specifications as variants like the 402F50033CLR, differing primarily in frequency tolerance and temperature grade. The series is engineered for high-volume consumer and industrial electronics.

Crystals Replacement Considerations

The 402F50022IAT is a direct substitute with identical electrical parameters but a different load capacitance specification (10pF vs 12pF). Verify oscillator circuit compatibility before swapping. Other 4-SMD 50MHz crystals may require retuning.
