SXT22410BB48-40.000M

Crystals Overview

The SXT22410BB48-40.000M is a surface-mount ceramic crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 40 MHz with a load capacitance of 10 pF. The device features a 4-SMD, no-lead package and supports an equivalent series resistance (ESR) of up to 50 Ohms. Frequency stability is rated at ±30 ppm, while frequency tolerance is specified at ±30 ppm. This component is designed for industrial applications requiring compact timing solutions.

Crystals Feature Summary

• Utilizes a 4-pad ceramic SMD package for enhanced grounding and EMI shielding compared to standard two-pin designs.
• Operates in fundamental mode, simplifying circuit design by eliminating the need for additional matching inductors.
• Provides high insulation resistance of 500 MΩ at 100 V DC for reliable industrial performance.

Crystals Applications

• Bluetooth and short-range wireless communication devices
• PCMCIA cards and modems
• Industrial control systems with high-density PCB layouts

Crystals Procurement Notes

Verify the specific suffix codes against the official datasheet to ensure correct load capacitance and tolerance levels. Confirm that the 4-SMD no-lead package matches your board footprint requirements. Check temperature range specifications if operating outside standard commercial limits.

Crystals Selection Notes

Select this model when space constraints require a 2.5x2.0 mm footprint but EMI immunity is critical. The four-terminal design offers superior noise rejection compared to two-terminal alternatives. Ensure the 10 pF load capacitance aligns with the host microcontroller's internal or external capacitor configuration.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic crystals. The series is characterized by small form factors suitable for portable and wearable electronics. It addresses the growing demand for robust timing components in dense electronic assemblies where signal integrity is paramount.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 10 pF load capacitance, and 4-SMD package. Verify that alternative components support similar ESR values and frequency stability ratings to maintain system performance without redesigning the oscillator circuit.
