SXT2248BB48-26.000M

Crystals Overview

The SXT2248BB48-26.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 26.000 MHz with a frequency stability and tolerance of ±30 ppm. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a 4-SMD, no lead package configuration, designed for compact electronic applications requiring precise timing signals.

Crystals Feature Summary

• Fundamental AT-cut quartz resonator design
• Four-terminal surface mount package structure
• Industrial-grade temperature range operation

Crystals Applications

• Bluetooth wireless communication modules
• Short-range wireless device timing
• PCMCIA interface circuits
• Industrial control systems

Crystals Procurement Notes

Verify the specific operating temperature range against project requirements, as datasheets may list -10°C to +60°C or -40°C to +85°C variants. Confirm the exact ESR value and load capacitance match the circuit design. Ensure the 4-SMD footprint aligns with the PCB layout. Request factory-sealed packaging to maintain component integrity during storage and handling.

Crystals Selection Notes

Select this component when a small 2520 footprint is required alongside robust electromagnetic interference shielding provided by the four-pad ground connection. It is suitable for designs needing fundamental mode operation without additional matching inductors. Consider the ±30 ppm stability sufficient for standard Bluetooth or Zigbee applications where tighter tolerances are not mandated.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic surface-mount crystals. The series offers various frequencies and stability options within a compact 2.5mm x 2.0mm package. The four-lead design distinguishes it from two-lead alternatives by providing better grounding and reduced radiation emissions for high-frequency digital and RF circuits.

Crystals Replacement Considerations

Direct substitutes include other SXT224 series parts with identical 26 MHz frequency and 8 pF load capacitance, such as SXT2248BB48-26.000MT if moisture sensitivity requires a different suffix. Verify that any replacement maintains the 4-SMD no-lead package and compatible ESR specifications.
