SXT14418CB17-4.000M

Crystals Overview

The SXT14418CB17-4.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a nominal frequency of 4.000 MHz with an initial frequency tolerance of ±25 ppm. The component features a load capacitance of 18 pF and a maximum equivalent series resistance (ESR) of 150 Ohms. It is housed in a 4-SOJ package with a 9.50 mm pitch, designed for surface mount technology applications requiring stable clock signals.

Crystals Feature Summary

• Surface mount design utilizing a 4-SOJ package configuration
• Stable oscillation characteristics with defined load capacitance parameters
• Compliant with lead-free and RoHS environmental standards

Crystals Applications

• Microcontroller unit clock sources
• Communication interface timing references
• General-purpose digital circuit synchronization

Crystals Procurement Notes

Verify the specific operating temperature range and stability specifications against project requirements, as datasheet variations may exist between different supplier listings. Confirm that the 4-SOJ package dimensions align with the target PCB footprint to ensure proper surface mount assembly. Cross-reference the manufacturer part number with official Suntsu Electronics documentation to validate authenticity and technical accuracy before finalizing procurement orders.

Crystals Selection Notes

Select this component when a low-cost, standard-frequency surface-mount crystal is required for basic timing applications. The 4.000 MHz frequency suits simple baud rate generation or slow-speed processor clocks. Consider the ±25 ppm tolerance limit; if higher precision is needed for long-term stability or wide temperature ranges, alternative models within the SXT144 series with tighter tolerances should be evaluated instead.

Crystals Part Context

This part belongs to the SXT144 series of plastic-sealed, four-pin surface-mount crystals from Suntsu Electronics. The series offers various frequency options and tolerance grades, catering to both consumer and industrial electronics. The SXT14418CB17 variant specifically denotes the 4-SOJ package style and associated electrical characteristics within this broader product family.

Crystals Replacement Considerations

Direct replacements must match the 4.000 MHz frequency, 18 pF load capacitance, and 4-SOJ package outline. Verify ESR limits and operating temperature ranges to ensure functional equivalence in the host circuit design.
