NX1255GB-8.000000MHZ-STD-CSA-1

Overview

The NX1255GB-8.000000MHZ-STD-CSA-1 is a surface-mount quartz crystal unit manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 8 MHz with a frequency stability and tolerance of ±50 ppm. The component utilizes a fundamental oscillation mode and is designed for a load capacitance of 12 pF. It features an equivalent series resistance (ESR) of 80 Ohms. The device is housed in a compact 4-SMD, No Lead package with dimensions of 1.2 mm x 1.6 mm and a maximum height of 0.55 mm. It supports operation within a temperature range of -20°C to +70°C and complies with RoHS3 standards.

Feature Summary

• Compact 1216 size surface-mount package suitable for space-constrained designs
• Fundamental mode oscillation for simplified circuit matching
• Compliant with RoHS3 environmental directives

Applications

• Clock sources for microcontrollers and processors
• Timing references for consumer audio/video equipment
• General-purpose oscillator circuits in portable electronics

Procurement Notes

Verify the specific suffix CSA-1 against the official NDK datasheet to confirm the exact packaging configuration and handling requirements. Ensure that the load capacitance requirement of the target oscillator circuit matches the 12 pF specification to maintain frequency accuracy. Confirm that the operating temperature range of -20°C to +70°C aligns with the environmental conditions of the final application to prevent performance degradation.

Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 80 Ohm ESR value must be compatible with the driving capability of the host oscillator circuit to ensure reliable startup. Consider the ±50 ppm tolerance if higher precision timing is not critical. Compare against the NX3225SA series if a larger footprint allows for tighter stability specifications such as ±15 ppm.

Part Context

This part belongs to the NX1255GB series of crystal units intended for OA and AV applications. It represents a standard commercial-grade solution from NDK, focusing on miniaturization while maintaining basic timing functions. The series is distinct from the higher-stability NX3225SA line, offering a cost-effective option for general electronic devices where extreme precision is not mandatory.
