SXT11413BB27-40.000M

Crystals Overview

The SXT11413BB27-40.000M is a 40 MHz fundamental AT-cut quartz crystal resonator manufactured by Suntsu Electronics, Inc. It features a frequency tolerance of ±30ppm and a frequency stability of ±30ppm over the operating temperature range of -20°C to +70°C. The device operates with a load capacitance of 13pF and exhibits a maximum equivalent series resistance (ESR) of 100 Ohms at this frequency. It is housed in a compact 4-SMD, No Lead package with dimensions of 1.6mm x 1.2mm.

Crystals Feature Summary

• Utilizes AT-cut fundamental resonance design for reliable oscillation startup
• Features a 4-pad surface mount footprint with integrated ground pads for enhanced electromagnetic interference immunity
• Complies with MIL-STD-883 mechanical and environmental testing standards

Crystals Applications

• Bluetooth wireless communication modules
• Wi-Fi enabled consumer electronics
• Industrial wireless sensor networks

Crystals Procurement Notes

Verify that the specific order matches the required load capacitance of 13pF and the -20°C to +70°C temperature rating. Ensure the PCB layout accommodates the 1.6mm x 1.2mm 4-SMD no-lead package dimensions. Confirm that the ESR specification of 100 Ohms aligns with the oscillator circuit requirements for stable operation.

Crystals Selection Notes

Select this component when a small form factor is critical for high-density board layouts. The 4-pad design offers superior noise rejection compared to 2-pad alternatives of similar size. Consider the ±30ppm stability if strict frequency accuracy is not required, or choose higher precision variants for more demanding timing applications.

Crystals Part Context

This part belongs to the SXT114 series of ultra-small crystals from Suntsu Electronics. The series is designed for space-constrained portable devices. The '13' in the model indicates the 13pF load capacitance, while 'BB' denotes the ±30ppm tolerance and stability ratings. The '27' suffix specifies the industrial temperature range.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 13pF load capacitance and 1.6x1.2mm 4-pad packages. Verify that alternative components meet the same 100 Ohm ESR limit and MIL-STD-883 reliability standards to ensure circuit compatibility.
