• AT-cut base resonance design ensuring reliable oscillation start-up
• Low ESR specification facilitating broader load capacitor selection margins
• Compliance with MIL-STD-883 mechanical and environmental testing standards

Crystals Applications

• Bluetooth wireless modules requiring Class B communication stability
• Industrial small wireless sensor networks
• WiFi enabled consumer electronics
• High-density circuit boards with limited component placement area

Crystals Procurement Notes

Verify the specific ordering suffix against official Suntsu documentation to confirm exact frequency tolerance and temperature grade. Ensure the procurement channel provides valid traceability for MIL-STD-883 compliance claims. Confirm moisture sensitivity level handling procedures prior to soldering, as the component is rated MSL 1. Cross-reference the part number with the latest datasheet to validate active status and availability.

Crystals Selection Notes

Select this component when a sub-2mm footprint is required alongside strict frequency stability needs. The 12pF load capacitance suits standard oscillator circuits without external trimming. Consider the ±20ppm stability for applications where temperature compensation is not feasible. Evaluate the 150 Ohm ESR limit against the oscillator circuit's drive level requirements to prevent over-driving or failure to start.

Crystals Part Context

This part belongs to the SXT114 series, characterized by ultra-small dimensions suitable for modern miniaturized electronics. The naming convention indicates the 1.6x1.2mm package size and specific electrical parameters. It serves as a direct replacement for larger crystals in space-constrained designs while maintaining industrial-grade reliability through rigorous environmental testing protocols defined by the manufacturer.

Crystals Replacement Considerations

Direct substitutes include other SXT114 variants with matching 1.6x1.2mm footprints and 12pF load capacitance. Verify that alternative parts maintain the same 150 Ohm ESR maximum and ±20ppm stability to ensure circuit compatibility. Check if adjacent frequencies like 24MHz or 25MHz are acceptable alternatives if the exact 27MHz is unavailable.
