SXT11412AA17-27.000M

Crystals Overview

The SXT11412AA17-27.000M is a 27 MHz AT-cut fundamental mode crystal oscillator manufactured by Suntsu Electronics, Inc. It features a ±50 ppm frequency tolerance and operates within a temperature range of -20°C to +70°C. The component utilizes a 4-SMD, No Lead package with dimensions of 1.6mm x 1.2mm. It has a load capacitance of 12 pF and an equivalent series resistance (ESR) of 150 Ohms. This device is designed for surface mount applications requiring compact footprints.

Crystals Feature Summary

• Compact 1.6mm x 1.2mm 4-pad surface mount footprint suitable for high-density PCB layouts
• AT-cut fundamental resonance design ensuring reliable oscillation startup characteristics
• Industrial-grade reliability compliant with MIL-STD-883 mechanical and environmental testing standards

Crystals Applications

• TWS (True Wireless Stereo) modules and Bluetooth audio devices
• WiFi and industrial wireless communication transceivers
• Consumer electronics requiring small form factor timing references

Crystals Procurement Notes

Verify the specific suffix '17' corresponds to the required -20°C to +70°C operating temperature range for your application environment. Confirm that the 150 Ohm ESR value aligns with your oscillator circuit's loading requirements to ensure proper startup conditions. Check RoHS compliance status if restricted substances are a concern for your manufacturing process.

Crystals Selection Notes

Select this component when space constraints necessitate a 1.6mm x 1.2mm footprint rather than larger standard packages. Consider the ±50 ppm tolerance sufficient for non-critical timing applications where higher precision like ±10 ppm is not required. Ensure the -20°C to +70°C temperature range meets the operational extremes of the target device.

Crystals Part Context

This part belongs to the SXT114 series of ultra-small crystals from Suntsu Electronics. The series is characterized by its 4-pad design which offers improved electromagnetic interference immunity compared to 2-pad alternatives. The naming convention indicates the series, package size, tolerance, stability, temperature range, and frequency.

Crystals Replacement Considerations

Direct substitutes must match the 1.6x1.2mm 4-SMD package, 27MHz frequency, and 12pF load capacitance. Verify ESR compatibility, as values above 150 Ohms may affect startup in marginal circuits. Cross-reference temperature ranges (-20°C to +70°C) to ensure environmental suitability.
