Crystals Overview

The SXT22411DD17-12.288M is a MHz crystal manufactured by Suntsu Electronics, Inc., operating at a nominal frequency of 12.288 MHz. It features a frequency stability of ±20ppm and utilizes an AT-cut fundamental resonance design. The component is housed in a compact 4-SMD, No Lead package with dimensions corresponding to the 2520 footprint. Key electrical specifications include a load capacitance of 11pF and an equivalent series resistance (ESR) of 120 Ohms. The device supports a standard operating temperature range of -10°C to +70°C, suitable for commercial applications requiring stable clock signals.

Crystals Feature Summary

• Four-terminal surface mount design provides grounding pins for improved electromagnetic interference shielding compared to two-pin variants.
• AT-cut fundamental resonance technology ensures simple oscillator circuit requirements without additional matching inductors.
• Compact 2520 footprint allows for high-density PCB layout in space-constrained wireless and industrial devices.

Crystals Applications

• Bluetooth low energy (BLE) modules
• Short-range wireless communication devices
• Industrial control systems with dense board layouts

Crystals Procurement Notes

Verify the specific suffix '17' against the manufacturer's official datasheet to confirm the exact temperature range and ESR tolerance, as suffix variations may indicate different environmental ratings or manufacturing batches. Ensure the ordering documentation explicitly references the 12.288 MHz frequency and 11pF load capacitance to avoid confusion with similar models in the SXT224 series that may have different stability grades or package options.

Crystals Selection Notes

Select this component when a small 2520 footprint is required alongside moderate frequency stability of ±20ppm. The four-pad configuration is preferred over two-pin alternatives in RF designs to minimize radiated emissions. Consider the -10°C to +70°C operating range; if wider industrial temperatures are needed, verify if other suffixes within the SXT224 family offer extended ranges while maintaining the same electrical parameters.

Crystals Part Context

This part belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series is characterized by its small 2520 package size and availability in various frequencies ranging from 12 MHz to 66 MHz. The SXT224 line is designed to replace larger through-hole crystals in modern portable electronics, offering comparable performance in a significantly reduced volume.

Crystals Replacement Considerations

Direct substitutes within the same series include SXT22411DD17-16.000M and SXT22411DD17-16.384M, which share identical package and base electrical characteristics but differ in frequency. Cross-brand replacements require careful verification of ESR, load capacitance, and drive level compatibility to ensure oscillator circuit stability.

Crystals FAQ

What is the maximum drive level for this crystal?

The typical maximum drive level for the SXT224 series is 100μW, though standard design practices often utilize lower levels between 10μW and 50μW to ensure longevity.

Does the 4-SMD package affect the mounting process?

Yes, the no-lead 4-SMD package requires standard surface mount reflow soldering processes. The four pads allow for direct connection to ground planes, which aids in thermal dissipation and EMI reduction during operation.
