SAX32412CA4A-20.000M

Crystals Overview

The SAX32412CA4A-20.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 20.000 MHz with a frequency tolerance of ±25 ppm. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a ceramic package measuring 3.2 mm x 2.5 mm in a 4-SMD, no-lead configuration. The device supports a wide operating temperature range from -40°C to +105°C and is supplied in tape and reel packaging for automated assembly processes.

Crystals Feature Summary

• Surface-mount ceramic construction for reliable high-frequency performance
• Wide industrial temperature rating suitable for demanding environments
• Standardized SMD footprint for efficient PCB integration

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators

Crystals Procurement Notes

Verify the specific suffix 'M' indicates tape and reel packaging rather than bulk or tray. Confirm the exact load capacitance requirement matches the target circuit design to ensure frequency accuracy. Check for RoHS compliance status if required by project specifications. Ensure the operating temperature range meets the environmental conditions of the final application.

Crystals Selection Notes

Select this component when a 20 MHz reference is required in a compact surface-mount form factor. The 12 pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the 80 Ohm ESR for drive level sensitivity. The wide temperature range makes it suitable for applications exceeding standard commercial limits.

Crystals Part Context

This part belongs to Suntsu Electronics' series of ceramic surface-mount crystals. Similar variants exist with different frequencies such as 12.000 MHz or different load capacitances. The numbering convention typically reflects package size, pin count, and electrical characteristics. These components are designed for general-purpose timing applications in consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes may include other 20 MHz 12 pF SMD crystals from manufacturers like Epson or NDK. Verify mechanical dimensions and pin compatibility before substitution. Electrical parameters such as ESR and frequency stability must be equal or superior. Cross-reference part numbers using distributor databases for availability.
