SAX2148CY4B-32.000M

Crystals Overview

The SAX2148CY4B-32.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 32 MHz with a frequency tolerance of ±25 ppm. The component features a load capacitance of 8 pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, No Lead package configuration designed for automated assembly processes.

Crystals Feature Summary

• Fundamental mode operation for stable frequency generation
• Surface-mount design compatible with standard SMT reflow processes
• Precision frequency stability suitable for timing applications

Crystals Applications

• Precision timing circuits in consumer electronics
• Clock signal generation for microcontrollers
• Communication device frequency references

Crystals Procurement Notes

Verify the specific suffix CY4B against the manufacturer's official datasheet to confirm the exact frequency tolerance and package dimensions. Ensure compatibility with the target PCB footprint and reflow temperature profile. Cross-reference the DigiKey part number 2388-SAX2148CY4B-32.000M-ND for accurate sourcing channels and availability status from authorized distributors.

Crystals Selection Notes

Select this component when a 32 MHz clock source with ±25 ppm stability is required. The 8 pF load capacitance must match the oscillator circuit requirements. Consider the 60 Ohm ESR for drive level sensitivity. The 4-SMD no-lead package dictates specific soldering pad layout constraints during PCB design.

Crystals Part Context

This part belongs to the SAX2148 series of ceramic surface-mount crystals from Suntsu Electronics. Similar variants include the SAX2148AX4B-32.000M which offers ±50 ppm tolerance. The series generally covers frequencies such as 30 MHz and 40 MHz within the same physical footprint family.

Crystals Replacement Considerations

The SAX2148AX4B-32.000M is a documented alternative within the same series, offering identical frequency and package but with ±50 ppm tolerance instead of ±25 ppm. Verify if the reduced stability meets system requirements before substitution.
