It operates at a nominal frequency of 19.2 MHz with a frequency tolerance of ±25ppm. The component features a load capacitance of 8pF and an equivalent series resistance (ESR) of 70 Ohms. It utilizes a 4-SMD, no-lead package configuration, providing a compact footprint suitable for modern electronic designs requiring precise timing signals.

Crystals Feature Summary

• Parallel fundamental quartz crystal operation for stable timing
• Compact 4-SMD no-lead surface-mount package design
• Defined load capacitance and ESR for circuit integration

Crystals Applications

• General-purpose timing signal generation in digital circuits
• Microcontroller clock sources requiring 19.2 MHz reference
• Embedded systems utilizing surface-mount assembly processes

Crystals Procurement Notes

Verify the specific suffix CB38 against official Suntsu documentation to confirm exact mechanical dimensions and terminal plating specifications. Ensure that the 8pF load capacitance matches the target oscillator circuit requirements to maintain the stated ±25ppm frequency tolerance. Cross-reference the 70 Ohm ESR value with system impedance constraints before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency is required within a tight surface-mount area constraint. The 8pF load capacitance suits circuits designed for lower capacitive loads, while the 70 Ohm ESR indicates moderate drive level sensitivity. Consider thermal stability ranges if operating in environments exceeding standard commercial temperature limits, as datasheet specifics should be confirmed.

Crystals Part Context

This part belongs to the SXT3248 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and package options, with the CB38 suffix denoting specific physical characteristics. It serves as a passive timing element, distinct from active oscillators, relying on external circuitry to sustain oscillation at the specified resonant frequency.

Crystals Replacement Considerations

Direct substitutes include other 19.2 MHz crystals with identical 4-SMD no-lead footprints, 8pF load capacitance, and comparable ESR values. Verify pin compatibility and frequency stability requirements when evaluating alternative manufacturers. Ensure any replacement maintains the parallel resonance mode to function correctly in existing designs.
