SXT1148EC27-40.000M

Crystals Overview

The SXT1148EC27-40.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., designed for precise frequency control applications. This component operates at a nominal frequency of 40.000 MHz with a standard tolerance of ±15 ppm. It features a load capacitance of 8 pF and an equivalent series resistance (ESR) of 100 Ohms. The device utilizes a 4-SMD, No Lead package configuration, suitable for automated assembly processes in compact electronic designs requiring stable clock signals.

Crystals Feature Summary

• Provides stable 40 MHz oscillation with ±15 ppm frequency tolerance
• Utilizes low-profile 4-SMD no-lead surface mount packaging
• Engineered for high reliability in precision timing circuits

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• Digital signal processing systems

Crystals Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Ensure that the 4-SMD footprint matches your PCB layout constraints. Confirm that the ±15 ppm tolerance meets the system's jitter and stability specifications. Request the official datasheet from Suntsu Electronics to validate electrical characteristics and mechanical dimensions for accurate integration.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required with moderate frequency stability. The 8 pF load capacitance must align with the connected oscillator circuit's input requirements. Consider the 100 Ohm ESR value for impedance matching purposes. The surface-mount form factor is ideal for space-constrained boards where traditional through-hole crystals cannot be accommodated.

Crystals Part Context

This part belongs to Suntsu Electronics' SXT1148 series of surface-mount crystals. The EC27 suffix typically denotes specific package dimensions and terminal configurations within this product line. These components are engineered to replace larger through-hole equivalents while maintaining similar electrical performance profiles for modern embedded systems.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 8 pF load capacitance, and 4-SMD package outline. Verify that alternative manufacturers offer comparable ±15 ppm tolerance and 100 Ohm ESR values to ensure circuit compatibility without redesign.
