SXT11411AA48-40.000M

Crystals Overview

The SXT11411AA48-40.000M is a surface-mount crystal component manufactured by Suntsu Electronics, Inc., designed for precision timing applications. It operates at a nominal frequency of 40 MHz with a frequency stability and tolerance of ±50ppm. The device features a load capacitance of 11pF and an equivalent series resistance (ESR) of 100 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm. This component is suitable for circuits requiring reliable clock signals.

Crystals Feature Summary

• Provides stable 40 MHz oscillation with ±50ppm frequency tolerance
• Compact 4-SMD no-lead surface mount design
• Optimized for low power consumption in portable electronics

Crystals Applications

• Microcontroller clock sources
• Communication module timing
• Digital signal processing circuits

Crystals Procurement Notes

Verify the manufacturer part number against official Suntsu Electronics documentation to ensure authenticity. Confirm that the received components match the specified 40 MHz frequency and 11pF load capacitance. Check for physical damage to the 4-SMD package before integration into PCB assemblies.

Crystals Selection Notes

Select this component when a 40 MHz reference is required with ±50ppm stability. Ensure the circuit design supports an 11pF load capacitance and can drive a 100 Ohm ESR. The small 1.60mm x 1.20mm footprint must be accommodated within the board layout constraints.

Crystals Part Context

This model belongs to the SXT11411 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies while maintaining consistent electrical characteristics such as 11pF load capacitance and 100 Ohm ESR across different variants.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 11pF load capacitance, 100 Ohm ESR, and compatible 4-SMD package dimensions. Verify pinout compatibility and thermal performance before substitution.
