SXT2248BB07-27.000M

Crystals Overview

The SXT2248BB07-27.000M is a parallel fundamental quartz crystal manufactured by Suntsu Electronics, Inc., designed for surface-mount applications. It operates at a nominal frequency of 27 MHz with a tolerance of ±30 ppm and a temperature stability of ±30 ppm across the commercial range of 0°C to +70°C. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 80 Ohms maximum. It utilizes a 4-SMD, no lead package configuration, commonly referred to as the 2520 footprint, suitable for compact electronic designs.

Crystals Feature Summary

• Four-pad ceramic surface-mount design providing enhanced grounding and electromagnetic interference shielding compared to two-pin alternatives.
• Fundamental AT-cut quartz construction ensuring stable oscillation without requiring additional matching inductors.
• Low drive level capability supporting power-efficient circuit architectures.

Crystals Applications

• Bluetooth low energy (BLE) modules
• Short-range wireless communication devices
• Industrial control systems with high-density board layouts

Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact electrical tolerances and temperature ranges. Ensure compatibility with reflow soldering profiles specified for 4-SMD packages. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Crystals Selection Notes

Select this component when space constraints require a 2.5x2.0 mm footprint alongside moderate frequency stability requirements. The four-terminal structure is advantageous for reducing radiated emissions in RF circuits. Consider higher precision variants if operation extends beyond the commercial temperature range or if tighter frequency drift limits are necessary.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade crystals from Suntsu Electronics. The series offers various frequency options and tolerance grades within the same physical package, allowing designers to standardize on a single footprint while adjusting performance specifications for different project tiers.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz crystals in the 4-SMD 2520 package with comparable ESR and load capacitance values. Verify that alternative manufacturers support the same operating temperature range and drive level specifications to maintain circuit reliability.
