SXT1148DB27-25.000M

Crystals Overview

The SXT1148DB27-25.000M is a 25 MHz fundamental AT-cut crystal oscillator manufactured by Suntsu Electronics, Inc. It features a compact 1.6 x 1.2 mm four-pad surface-mount package with no lead construction. The component provides a frequency tolerance of ±20 ppm and operates within a temperature range of -20°C to +70°C. It utilizes an 8 pF load capacitance and exhibits a maximum equivalent series resistance (ESR) of 150 Ohms at this frequency. The device is RoHS compliant and designed for high-reliability applications requiring stable timing signals in space-constrained environments.

Crystals Feature Summary

• Compact 1.6x1.2mm four-pad SMD package with two integrated ground pads for enhanced interference immunity
• Fundamental AT-cut design ensuring reliable oscillation startup across operating conditions
• Industrial-grade reliability with MIL-STD-883 mechanical and environmental testing compliance
• Moisture Sensitivity Level 1 classification allowing direct soldering without pre-baking

Crystals Applications

• TWS (True Wireless Stereo) module clock sources
• Bluetooth Class B communication devices
• WiFi industrial wireless modules
• High-density PCB timing circuits

Crystals Procurement Notes

Verify the specific suffix '27' corresponds to the required -20°C to +70°C temperature range for your application environment. Confirm that the 150 Ohm ESR limit aligns with your circuit's oscillator design requirements. Ensure compatibility with the 8 pF load capacitance specification during schematic design. Check for RoHS compliance documentation if required by your manufacturing standards.

Crystals Selection Notes

Select this component when space constraints require a footprint smaller than standard 0402 resistors but higher noise immunity than two-pad variants. Consider the ±20 ppm tolerance sufficient for Bluetooth Class B applications without additional temperature compensation. Evaluate the 150 Ohm ESR against your oscillator circuit's drive level limitations to prevent over-driving the crystal. Verify that the -20°C lower temperature limit meets your operational environment specifications.

Crystals Part Context

This part belongs to the SXT114 series of ultra-small crystals from Suntsu Electronics. The series covers frequencies from 24 MHz to 54 MHz, targeting modern wireless communication standards. The naming convention indicates the 1.6x1.2mm package size and specific performance grades. This model represents a balance between miniaturization and electrical stability for consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes must match the 1.6x1.2mm four-pad footprint and 25 MHz frequency. Verify equivalent ESR values below 150 Ohms to ensure circuit compatibility. Check that replacement parts offer similar thermal stability and MSL ratings. Cross-reference pinout configurations to confirm ground pad alignment.
