SXT22410FB27-48.000M

Crystals Overview

The SXT22410FB27-48.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., designed for precision timing applications. It operates at a fundamental frequency of 48 MHz with a nominal load capacitance of 10 pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a frequency tolerance of ±10 ppm and a frequency stability of ±30 ppm over the operating temperature range of -20°C to +70°C. Packaged in a compact 4-SMD, no-lead form factor, it supports base mode operation suitable for space-constrained circuit designs.

Crystals Feature Summary

• Utilizes a 4-pad SMD package design that provides grounding pins for enhanced electromagnetic interference shielding compared to standard two-pin variants.
• Operates in fundamental AT-cut base mode, simplifying oscillator circuit requirements by eliminating the need for additional matching inductors.

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 the ordering documentation matches the required load capacitance and ESR specifications for the target application circuit. Confirm compliance with RoHS standards if environmental regulations apply to the end product.

Crystals Selection Notes

Select this component when a small footprint is critical but superior noise immunity is required over standard two-pin crystals. The four-terminal design facilitates direct connection to ground planes, reducing radiated emissions. Consider the ±10 ppm initial tolerance for applications requiring tight frequency accuracy within the industrial temperature window.

Crystals Part Context

This part belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series is engineered for wireless and portable electronics where size constraints and signal integrity are paramount. The 2520 package dimensions offer a balance between miniaturization and thermal performance for consumer and industrial hardware.

Crystals Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 10 pF load capacitance, and 4-SMD no-lead package. Verify that alternative components support the same ±10 ppm tolerance and -20°C to +70°C operating range to ensure functional compatibility without circuit redesign.

Crystals FAQ

Does the SXT22410FB27-48.000M require external matching inductors?

No, as it operates in the fundamental base mode, it does not require the additional matching inductors typically needed for overtone crystals.

What is the benefit of the 4-pad package over a 2-pad package?

The extra pads allow for connection to the ground plane, providing better electromagnetic interference shielding and lower radiated emissions.
