NX1255GB-4.000000MHZ

Overview

The NX1255GB-4.000000MHZ is a surface-mount MHz crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 4.000000 MHz with a frequency stability of ±50ppm. The component features a load capacitance of 12pF and an equivalent series resistance of 120 Ohms. It is designed for an operating temperature range of -10°C to +70°C. The device utilizes a 4-SMD, No Lead package configuration.

Feature Summary

• Surface-mount design for automated assembly
• Lead-free construction compliant with environmental standards
• Stable frequency performance within specified industrial temperature limits

Applications

• General-purpose clock signal generation in electronic circuits
• Microcontroller system timing references
• Industrial control equipment requiring standard frequency stability

Procurement Notes

Verify current availability status as the product may be discontinued or subject to supply constraints. Confirm that the specific ordering suffix matches the required frequency tolerance and package variant. Ensure compatibility with existing PCB footprint designs. Check for any regional tariff implications if shipping to the United States. Request official datasheets for final electrical parameter validation before integration.

Selection Notes

Select this component when a 4 MHz reference signal is required for SMD-based designs. Consider the ±50ppm stability limit against system timing requirements. Evaluate the -10°C to +70°C operating range against environmental conditions. Compare the 12pF load capacitance with oscillator circuit specifications. Assess the 120 Ohm ESR against driver strength capabilities.
