SXT22418EA16-24.000M

Crystals Overview

The SXT22418EA16-24.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., designed for compact electronic applications. It operates at a fundamental frequency of 24.000 MHz with an 18 pF load capacitance specification. The component utilizes a 4-pad lead-free SMD package to facilitate efficient PCB layout and grounding. Key electrical characteristics include a maximum equivalent series resistance (ESR) of 80 Ohms and a frequency stability tolerance of ±50 ppm. The device is rated for operation within a temperature range of -10°C to +60°C, suitable for commercial-grade environments requiring reliable clock signal generation.

Crystals Feature Summary

• Four-pad surface mount design enhances electromagnetic interference shielding and grounding stability compared to standard two-pin configurations.
• Fundamental AT-cut quartz resonator technology ensures simple oscillation circuit requirements without the need for additional matching inductors.
• Lead-free construction supports compliance with environmental standards while maintaining robust mechanical integrity for automated assembly processes.

Crystals Applications

• Bluetooth low energy (BLE) communication modules
• Short-range wireless sensor networks
• Industrial control systems with moderate thermal constraints
• Portable consumer electronics requiring compact clock sources

Crystals Procurement Notes

Verify that the specific application environment remains within the specified -10°C to +60°C operating temperature range, as this model is not rated for industrial or extended temperature extremes. Confirm that the system's load capacitance matches the 18 pF requirement to ensure accurate frequency performance. Ensure PCB footprint compatibility with the 4-pad SMD package dimensions prior to ordering. Cross-reference the ±50 ppm stability tolerance against the host microcontroller's clock input specifications to guarantee system timing accuracy.

Crystals Selection Notes

Select this component when space constraints necessitate a small 2520 footprint but electromagnetic compatibility requires superior grounding via a four-terminal design. Choose this part over higher-stability variants if the application does not demand tighter frequency tolerances below ±50 ppm. Consider alternative models from the same series if the operational environment exceeds the commercial temperature limits or requires lower ESR values for specific oscillator topologies.

Crystals Part Context

This component belongs to the SXT224 series of ceramic surface-mount crystals produced by Suntsu Electronics. The series is engineered to address the growing demand for miniaturized clock sources in wireless and IoT devices. The SXT224 family distinguishes itself through its four-pad architecture, which provides better noise immunity than traditional two-lead counterparts. This specific model represents a standard commercial-grade option optimized for cost-sensitive mass production applications.

Crystals Replacement Considerations

Direct substitutes must match the 24.000 MHz frequency, 18 pF load capacitance, and 4-pad SMD package. Verify that any replacement maintains the ±50 ppm stability and -10°C to +60°C temperature range. Check ESR specifications to ensure compatibility with the existing oscillator circuit. Models such as SXT22418AA16-24.000M may offer different stability grades but require verification of pinout and dimensional equivalence.
