It operates at a fundamental frequency of 37.4 MHz with a frequency tolerance of ±25 ppm. The component features a load capacitance of 21 pF and an equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, No Lead package, suitable for automated assembly processes in modern PCB designs.

Crystals Feature Summary

• Provides stable 37.4 MHz frequency output with ±25 ppm tolerance
• Utilizes a 4-SMD no-lead surface mount package for space efficiency
• Designed for integration into digital signal processing and microcontroller systems

Crystals Applications

• Microcontroller clock sources
• Digital signal processor timing references
• Motor control system oscillators

Crystals Procurement Notes

Verify the specific suffix 'CB16' against the manufacturer's latest datasheet to confirm pinout and mechanical dimensions. Ensure compatibility with the target circuit's load capacitance requirements of 21 pF. Cross-reference the ESR value of 60 Ohms with oscillator design specifications to guarantee reliable startup conditions.

Crystals Selection Notes

Select this component when a 37.4 MHz reference is required in a small form factor. The ±25 ppm tolerance suits applications where moderate frequency stability is acceptable. The 4-SMD package facilitates high-volume manufacturing. Consider the 21 pF load capacitance requirement when designing the PCB trace layout and external capacitor values.

Crystals Part Context

This part belongs to the SXT224 series of crystals from Suntsu Electronics. The series offers various frequencies and packages. The SXT22421CB16 variant specifically targets applications needing a 37.4 MHz signal in a leadless surface-mount configuration, distinguishing it from through-hole or larger package alternatives in the same product line.

Crystals Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, 21 pF load capacitance, and 4-SMD no-lead footprint. Verify that alternative components meet the ±25 ppm tolerance and 60 Ohm ESR specifications to ensure circuit performance parity.
