SXT14420CB48-7.3728M

Crystals Overview

The SXT14420CB48-7.3728M is a fundamental-mode quartz crystal resonator manufactured by Suntsu Electronics, Inc. It operates at a nominal frequency of 7.3728 MHz with a frequency tolerance of ±25 ppm. The component features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 100 Ohms maximum. It is housed in a 4-SOJ surface-mount package with a 9.50 mm pitch. This device is designed for precision timing applications requiring stable oscillation.

Crystals Feature Summary

• Fundamental-mode operation for precise frequency stability
• Surface-mount 4-SOJ package design for automated assembly
• Low equivalent series resistance for efficient circuit driving

Crystals Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Digital signal processing systems

Crystals Procurement Notes

Verify the specific suffix CB48 against the manufacturer's official datasheet to confirm pin configuration and mechanical dimensions. Ensure the required frequency tolerance of ±25 ppm meets system specifications. Cross-reference the 20 pF load capacitance with the oscillator circuit design to guarantee accurate frequency generation without external trimming adjustments.

Crystals Selection Notes

Select this component when a 7.3728 MHz fundamental frequency is required for baud rate compatibility or specific clock division needs. The 4-SOJ package is suitable for standard surface-mount reflow processes. Consider the ±25 ppm tolerance relative to the overall system timing budget and environmental temperature variations during operation.

Crystals Part Context

This part belongs to the Suntsu SXT14420 series of surface-mount crystals. The series offers various frequencies and packages tailored for compact electronic designs. The SXT14420CB48 variant specifically utilizes the SOJ form factor, distinguishing it from larger through-hole or smaller chip-style alternatives within the broader product line.

Crystals Replacement Considerations

Direct replacements must match the 7.3728 MHz frequency, 20 pF load capacitance, and 4-SOJ package dimensions. Verify that substitute components meet or exceed the ±25 ppm tolerance and 100 Ohm ESR limits to maintain circuit performance.
