SXT32420DD17-19.200M

Crystals Overview

The SXT32420DD17-19.200M is a surface-mount quartz crystal resonator manufactured by Suntsu Electronics, Inc. It operates at a nominal frequency of 19.2 MHz with a frequency tolerance of ±20 ppm. The component features a load capacitance of 20 pF and a maximum equivalent series resistance (ESR) of 70 Ohms. It is housed in a 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm. The device supports a standard operating temperature range of 0°C to +70°C.

Crystals Feature Summary

• Utilizes a 4-terminal surface mount ceramic package for enhanced electromagnetic interference immunity compared to two-lead designs.
• Provides stable frequency generation suitable for precision timing applications in industrial environments.
• Designed for compatibility with standard high-temperature reflow soldering processes without requiring pre-baking.

Crystals Applications

• Industrial gateway Ethernet PHY clock synchronization
• High-reliability microcontroller system clocks
• Wireless communication module timing sources

Crystals Procurement Notes

Verify the specific suffix 'DD17' against the official Suntsu datasheet to confirm the exact temperature range and tolerance specifications. Ensure the required load capacitance matches the target oscillator circuit design. Confirm that the 4-SMD package footprint aligns with the PCB layout constraints before finalizing the bill of materials.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency is required with ±20 ppm stability. The 4-terminal package is preferred for applications demanding superior noise rejection. Consider the 0°C to +70°C operating range; if wider industrial temperatures are needed, verify alternative suffixes such as 'CC48' which support -40°C to +85°C.

Crystals Part Context

This part belongs to the SXT324 series of surface-mount crystals from Suntsu Electronics. The series covers frequencies from 8 MHz to 70 MHz in fundamental mode. The 3225 package size is a standard industry form factor, balancing compactness with performance for embedded systems and consumer electronics.

Crystals Replacement Considerations

For wider temperature requirements, consider the SXT32420CC48 variant which supports -40°C to +85°C. For tighter tolerance needs, check the SXT32420DC07 model offering ±25 ppm or lower. Direct pin-compatible substitutes require matching the 19.2 MHz frequency, 20pF load capacitance, and 4-SMD package.
