• High frequency stability of ±10 ppm ensures precise timing accuracy
• Wide industrial operating temperature range from -40°C to +85°C

Crystals Applications

• Microcontroller clock sources requiring stable timing references
• Communication modules utilizing 37.4 MHz carrier frequencies
• Industrial control systems operating in variable thermal environments

Crystals Procurement Notes

Verify the specific suffix 'CDR' against official CTS documentation to confirm the 18 pF load capacitance specification, as other variants in the 402 series may utilize different capacitance values such as 8 pF or 10 pF. Ensure the selected part matches the required ESR of 60 Ohms and the 4-SMD 1.6x1.2 mm package dimensions for proper integration into the target circuit design.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental mode crystal is required with tight ±10 ppm stability constraints. The 18 pF load capacitance must align with the oscillator circuit's external capacitor configuration. Consider the 60 Ohm ESR value for drive level sensitivity and the -40°C to +85°C temperature range for environmental suitability compared to commercial grade alternatives.

Crystals Part Context

This component belongs to the CTS 402 Series of miniature quartz crystals. The series offers various frequency codes and package options tailored for high-density electronics. The 402F37411CDR specifically addresses needs for stable, low-profile timing solutions in modern consumer and industrial devices where board space is limited.

Crystals Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the 402F37411CKT and 402F37411CAR. Verify that these alternatives maintain the identical 18 pF load capacitance, 60 Ohm ESR, and ±10 ppm tolerance before substitution.
