SXT32418CA38-19.200M

Crystals Overview

The SXT32418CA38-19.200M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 19.2 MHz with a frequency tolerance of ±25 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 70 Ohms. It is housed in a compact 4-SMD, No Lead package, designed for integration into space-constrained electronic circuits requiring precise timing signals.

Crystals Feature Summary

• Provides stable 19.2 MHz oscillation with tight frequency tolerance
• Utilizes a lead-free 4-SMD surface-mount package for automated assembly
• Designed for low impedance applications with specified ESR characteristics

Crystals Applications

• Precision timing circuits in consumer electronics
• Clock generation for microcontrollers and digital signal processors
• Communication interface synchronization modules

Crystals Procurement Notes

Verify the specific suffix CA38 against the manufacturer's official datasheet to confirm pinout compatibility and mechanical dimensions. Ensure that the required frequency stability meets the system design specifications before procurement. Cross-reference the RoHS compliance status with current regulatory requirements for the target market.

Crystals Selection Notes

Select this component when a 19.2 MHz reference is required with ±25 ppm accuracy. Consider the 18 pF load capacitance requirement for circuit matching. Evaluate the 70 Ohm ESR against the oscillator circuit's drive level limitations to prevent over-driving the crystal. Confirm the 4-SMD footprint matches the PCB layout constraints.

Crystals Part Context

This part belongs to the SXT32418 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options within a standardized small outline package. The CA38 suffix typically denotes specific packaging or material variations within the product line, distinguishing it from other variants like BB38 or DB38 which may have different tolerances or stability ratings.

Crystals Replacement Considerations

Direct substitutes include SXT32418BB38-19.200M, though it has a ±30 ppm tolerance. Other frequencies in the same package require re-evaluation of the clock circuit design. Verify that any alternative maintains the 18 pF load capacitance and compatible ESR values.
