It features a load capacitance of 10 pF and a frequency stability of ±10 ppm. The component utilizes a 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm x 0.55mm maximum height. It exhibits an equivalent series resistance (ESR) of 60 Ohms and supports base harmonic operation within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Compact 4-SMD no-lead surface mount design for automated assembly
• Fundamental mode operation ensuring precise timing accuracy
• RoHS compliant construction suitable for lead-free manufacturing processes

Crystals Applications

• Microcontroller clock sources requiring stable timing references
• Communication modules utilizing 38.4 MHz baud rates
• Industrial control systems needing reliable oscillation in moderate temperature ranges

Crystals Procurement Notes

Verify the specific ESR value of 60 Ohms against circuit requirements, as this differs from other variants in the 402 series. Confirm that the 10 pF load capacitance matches the host oscillator circuit's external capacitor configuration to ensure accurate frequency tuning. Check RoHS3 compliance status if required by specific environmental regulations.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency is strictly required for communication or data transfer protocols. The 60 Ohm ESR must be compatible with the driving circuit's power limitations. Ensure the 4-SMD footprint fits the PCB layout constraints compared to larger packages. Consider the ±10 ppm stability sufficient for the target application's jitter tolerance.

Crystals Part Context

This part belongs to the CTS 402 Series of high-stability crystals designed for general-purpose timing applications. The series offers various frequencies and package sizes, with the 402F38411CAR specifically addressing the need for compact SMD solutions in space-constrained electronic designs.

Crystals Replacement Considerations

The 402F32011CAR is a listed alternative but operates at 32 MHz, making it unsuitable for direct frequency substitution. Verify pin compatibility and electrical parameters before considering any cross-references.
