NX2016AB-40MHZ SW2

Overview

The NX2016AB-40MHZ SW2 is a surface-mount crystal unit manufactured by NDK, designed for compact wireless applications. It features a standard 2016 package with dimensions of 2.0mm x 1.6mm and a height of 0.50mm. The nominal frequency is 40MHz, operating in fundamental mode. Key electrical parameters include a load capacitance (CL) of 7pF, a maximum equivalent series resistance (R1) of 60Ω, and a maximum drive level of 10μW. Frequency tolerance is ±10ppm at 25°C, with a total frequency stability of ±10ppm over the -20°C to +70°C temperature range.

Feature Summary

• Optimized for small form factor designs with a low-profile 2016 SMD package.
• Engineered specifically for Wireless LAN and short-range communication systems.
• Provides high frequency stability within industrial-grade temperature limits.

Applications

• Wireless LAN modules
• Bluetooth devices
• IoT terminals

Procurement Notes

Verify the specific ordering suffix against the official NDK datasheet to ensure correct load capacitance and tolerance specifications. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the PCB layout adheres to recommended pad dimensions to prevent soldering defects due to the small footprint.

Selection Notes

Select this component when space constraints require a 2016 footprint while maintaining strict frequency accuracy for wireless protocols. Verify that the host MCU's oscillator circuit can support the specified 60Ω ESR limit. Ensure the design environment stays within the -20°C to +70°C operational range to guarantee the stated ±10ppm stability.

Part Context

This part belongs to the NX2016 series, a family of miniature crystal units developed by NDK for modern portable electronics. The series addresses the industry demand for smaller clock sources without compromising performance. The AB variant typically denotes specific tolerance and temperature characteristics tailored for consumer and industrial wireless standards.

Replacement Considerations

Direct substitutes must match the 2016 footprint, 40MHz frequency, 7pF load capacitance, and ±10ppm stability. Cross-reference ESR limits and drive level sensitivity with alternative manufacturers' datasheets to ensure circuit compatibility.
