SXT22419EB48-14.7456M

Crystals Overview

The SXT22419EB48-14.7456M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., operating at a fundamental frequency of 14.7456 MHz. It features a 4-SMD, no-lead package design with a load capacitance of 19 pF and an equivalent series resistance (ESR) of 120 Ohms. The component offers a frequency tolerance of ±15 ppm, ensuring precise timing stability for sensitive electronic circuits. This industrial-grade device is engineered for reliable performance in compact applications requiring stable clock signals.

Crystals Feature Summary

• Utilizes a 4-pad surface-mount package to provide enhanced grounding and electromagnetic interference shielding compared to standard two-pin designs.
• Operates in fundamental mode, simplifying circuit design by eliminating the need for additional matching inductors required by overtone crystals.
• Delivers high frequency stability with a ±15 ppm tolerance, suitable for applications demanding strict timing accuracy.

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 load capacitance and ESR requirements against your circuit schematic before ordering. Confirm that the 4-SMD footprint matches your PCB land pattern. Ensure the ±15 ppm tolerance aligns with your system's timing budget. Check for any specific handling or storage requirements outlined in the manufacturer's datasheet to maintain component integrity during assembly.

Crystals Selection Notes

Select this component when space constraints necessitate a small 2520 footprint but superior EMC performance is critical. The four-terminal design provides better noise immunity than two-terminal alternatives, making it ideal for 2.4 GHz radio interfaces. Consider the 19 pF load capacitance to ensure proper oscillation without external capacitors if the circuit impedance matches. Evaluate the 120 Ohm ESR against your driver strength capabilities.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic SMD crystals from Suntsu Electronics. The series is characterized by its small 2.5 x 2.0 mm package and robust construction for harsh environments. Variants within the series differ primarily in frequency, tolerance, and load capacitance, allowing designers to tailor timing solutions for specific wireless and industrial protocols while maintaining consistent physical dimensions.

Crystals Replacement Considerations

Direct substitutes include other SXT224 series variants such as SXT22419DD48-14.7456M or SXT22419BB48-14.7456M, which share the same package and frequency but offer different tolerances. Cross-reference pinout and electrical parameters carefully when substituting with components from other manufacturers to ensure compatibility with existing RF stages.
