SXT22418AA38-14.7456M

Crystals Overview

The SXT22418AA38-14.7456M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., designed for precision timing applications in compact electronic systems. It operates at a fundamental frequency of 14.7456 MHz with a load capacitance of 18 pF and a frequency stability of ±50 ppm. The component utilizes an AT-cut resonator housed in a 4-SMD, No Lead package measuring 2.50mm x 2.00mm with a maximum seated height of 0.80mm. It supports a standard operating temperature range of -10°C to +60°C and complies with RoHS standards for lead-free assembly.

Crystals Feature Summary

• Four-pad ceramic surface mount design provides enhanced electromagnetic interference shielding compared to two-pin variants.
• AT-cut fundamental resonance ensures stable oscillation without requiring additional matching inductors.
• Compact 2.50mm x 2.00mm footprint enables high-density board layout for space-constrained devices.

Crystals Applications

• Bluetooth low energy (BLE) wireless communication modules
• Short-range wireless positioning tags
• Industrial control systems with dense circuit layouts

Crystals Procurement Notes

Verify the specific suffix AA38 against the manufacturer's official datasheet to confirm the exact frequency tolerance and temperature range specifications. Ensure that the selected variant meets the thermal requirements of the target application environment. Cross-reference the pin configuration and electrical parameters with the system schematic before finalizing procurement orders.

Crystals Selection Notes

Select this component when a small form factor is required alongside basic frequency stability for consumer or light industrial electronics. The four-terminal structure offers improved noise immunity over standard two-terminal crystals. Consider higher stability grades if the application demands tighter frequency drift limits across varying environmental conditions.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic surface-mount crystals from Suntsu Electronics. The series is engineered to address the spatial and electromagnetic challenges of modern wireless devices. It serves as a direct replacement for legacy through-hole or larger surface-mount oscillators in portable and wearable technology designs.

Crystals Replacement Considerations

Direct substitutes include other SXT224 series variants with compatible frequencies and package dimensions. Verify equivalent load capacitance and drive level specifications to ensure circuit compatibility during cross-brand or alternative sourcing transitions.
