SXT32419DD07-12.000M

Crystals Overview

The SXT32419DD07-12.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a nominal frequency of 12.000 MHz with a frequency tolerance of ±20ppm. The component features a load capacitance of 19pF and an equivalent series resistance (ESR) of 100 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 3.2mm x 2.5mm. The device is designed for surface mount mounting methods.

Crystals Feature Summary

• Surface-mount design in a compact 4-SMD no lead package
• Frequency stability maintained within ±20ppm tolerance
• Optimized for standard load capacitance requirements

Crystals Applications

• General purpose clock generation circuits
• Microcontroller system timing references
• Communication module frequency sources

Crystals Procurement Notes

Verify the specific operating temperature range against application requirements, as datasheets may list variations such as commercial or industrial grades. Confirm that the 100 Ohm ESR aligns with the oscillator circuit design specifications to ensure proper startup and stability. Ensure the 19pF load capacitance matches the host device's input capacitance settings.

Crystals Selection Notes

Select this component when a 12 MHz reference signal is required in a space-constrained surface-mount layout. The 100 Ohm ESR value suits standard parallel resonant circuits. Consider the ±20ppm tolerance if higher precision is needed, as other variants may offer tighter tolerances. Verify the package footprint compatibility with existing PCB silkscreen and copper pad designs.

Crystals Part Context

This part belongs to the SXT324 series of crystals from Suntsu Electronics. The series typically includes various frequencies and package sizes. The '19' in the model number often indicates the pin configuration or internal structure variant. This specific model is a fixed-frequency crystal intended for stable clocking applications rather than programmable oscillators.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz crystals with identical 3.2x2.5mm 4-SMD packages, 19pF load capacitance, and similar ESR values. Cross-reference with Suntsu part numbers like SXT32419DD38-12.000M if package differences are acceptable. Verify that alternative manufacturers provide comparable frequency stability and temperature performance characteristics.
