SXT32421CA48-13.000M

Crystals Overview

The SXT32421CA48-13.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 13.000 MHz with a load capacitance of 21 pF and an equivalent series resistance of 100 Ohms. The component utilizes a 4-SMD, No Lead package with dimensions of 3.2 mm x 2.5 mm. Frequency tolerance is specified at ±25 ppm, while frequency stability ranges from -40°C to +85°C with a variation of ±50 ppm across the temperature range.

Crystals Feature Summary

• Provides precise timing signals for digital circuits
• Utilizes ceramic construction for durability
• Designed for surface-mount assembly processes

Crystals Applications

• Microcontroller clock sources
• Communication module timing
• Embedded system oscillators

Crystals Procurement Notes

Verify the specific suffix CA48 against official Suntsu documentation to confirm pinout and mounting specifications. Ensure the operating environment remains within the stated -40°C to +85°C range to maintain the ±50 ppm stability guarantee. Cross-reference the 21 pF load capacitance requirement with the target circuit design to prevent frequency deviation issues during integration.

Crystals Selection Notes

Select this component when a 13 MHz reference signal is required in a compact 3.2mm x 2.5mm footprint. The ±25 ppm tolerance suits applications demanding moderate precision without requiring higher-cost oven-controlled alternatives. Consider the 100 Ohm ESR limits when designing the oscillator circuit's feedback network to ensure reliable startup conditions.

Crystals Part Context

This part belongs to the SXT32421 series of ceramic surface-mount crystals. The series offers various frequency options including 14.31818 MHz and 14.7456 MHz variants. These components are engineered for general-purpose timing applications where size constraints and cost-effectiveness are primary design drivers alongside basic frequency accuracy requirements.

Crystals Replacement Considerations

Direct substitutes include other 13 MHz crystals in the same 3225 package with matching 21 pF load capacitance. Verify that alternative parts meet the same ±25 ppm tolerance and 100 Ohm ESR specifications. Ensure the replacement maintains the -40°C to +85°C operational temperature range for environmental compatibility.
