NX1255GB-20.000000MHZ

Overview

The NX1255GB-20.000000MHZ is a surface-mount crystal unit manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 20.0000 MHz with a frequency stability and tolerance of ±50ppm. The component features a load capacitance of 12pF and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a 4-SMD, No Lead package configuration. The specified operating temperature range extends from -10°C to 70°C. This device is designed for precision timing applications within consumer electronics.

Feature Summary

• Surface-mount construction utilizing a 4-SMD, No Lead package design
• Frequency stability maintained at ±50ppm under standard conditions
• Compatible with lead-free manufacturing processes and RoHS compliance standards

Applications

• Consumer electronics timing circuits
• OA equipment clock generation
• AV system synchronization

Procurement Notes

Verify the current production status prior to ordering, as this specific part number may be discontinued or subject to end-of-life restrictions. Confirm that the required operating temperature range of -10°C to 70°C aligns with the target application environment. Ensure compatibility with the 12pF load capacitance specification in the circuit design. Check for any applicable tariff regulations if shipping to the United States. Validate RoHS compliance requirements against project specifications.

Selection Notes

Select this component when a 20MHz reference signal is required for general-purpose consumer or office automation applications. The ±50ppm stability is suitable for non-critical timing interfaces. Consider alternative models if the application demands operation below -10°C or above 70°C. Verify that the 50 Ohm ESR matches the oscillator circuit's drive level requirements. Ensure the 4-SMD footprint fits within the available PCB area constraints.
