SXT22417BA27-24.000M

Crystals Overview

The SXT22417BA27-24.000M is a surface-mount MHz crystal manufactured by Suntsu Electronics, Inc., operating at a nominal frequency of 24.000 MHz. It utilizes an AT-cut fundamental mode design within the SXT224 series. The component features a 4-SMD, no-lead package with dimensions of 2.5 x 2.0 mm. Key electrical specifications include a load capacitance of 17 pF and an equivalent series resistance (ESR) of 80 Ohms maximum. Frequency stability is rated at ±30 ppm, with a frequency tolerance of ±25 ppm. The device supports a base harmonic operation mode and is designed for industrial temperature ranges.

Crystals Feature Summary

• Four-terminal surface mount configuration provides enhanced electromagnetic interference shielding compared to two-pin alternatives.
• AT-cut fundamental resonance design simplifies oscillator circuit requirements by eliminating the need for additional matching inductors.

Crystals Applications

• Bluetooth low energy (BLE) communication modules
• Zigbee wireless sensor networks
• Industrial control systems with high-density board layouts

Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to ensure exact frequency and tolerance alignment. Confirm that the 4-SMD package variant matches the target PCB footprint, as pin configurations differ from standard two-lead crystals. Cross-reference the ESR and load capacitance values with the host microcontroller or oscillator circuit datasheet to guarantee reliable startup conditions under specified thermal constraints.

Crystals Selection Notes

Select this component when space-constrained designs require superior noise immunity through four-terminal grounding. The fundamental AT-cut architecture offers lower phase noise and simpler biasing than overtone modes. Ensure the application environment remains within the supported operational temperature range to maintain the stated ±30 ppm stability. This part is suitable for projects where EMI reduction is critical for maintaining signal integrity in crowded RF environments.

Crystals Part Context

This model belongs to the SXT224 series, which focuses on compact industrial-grade ceramic resonators. The series addresses the limitations of smaller two-lead packages by integrating ground pins for better shielding. It serves as a specialized solution for modern wearable devices and IoT nodes where both physical size and electromagnetic performance are primary design drivers.

Crystals Replacement Considerations

Direct substitutes must match the 24 MHz frequency, 17 pF load capacitance, and 4-SMD no-lead package. Verify that alternative components support the same 80 Ohm ESR limit and ±30 ppm stability to ensure circuit compatibility without redesign.
