NX2016AB-26MHZ SB1

Overview

The NDK NX2016AB-26MHZ SB1 is a surface-mount quartz crystal oscillator designed for compact electronic applications. It operates at a nominal frequency of 26 MHz with a load capacitance of 7 pF. The device features a fundamental oscillation mode and utilizes a 4-SMD, no-lead package measuring 2.0 mm x 1.6 mm x 0.50 mm. Key electrical specifications include a maximum equivalent series resistance (ESR) of 80 Ohms and a frequency tolerance of ±10 ppm at 25°C. This component serves as a precise clock source for wireless communication modules requiring small form factors.

Feature Summary

• Ultra-small 2.0x1.6mm SMD footprint suitable for space-constrained designs
• Fundamental oscillation mode eliminates need for overtone suppression circuits
• Low profile construction with 0.50mm height for thin device integration

Applications

• Bluetooth Low Energy (BLE) modules
• Compact IoT sensor nodes
• Wireless LAN devices
• Wearable electronics

Procurement Notes

Verify the specific suffix 'SB1' against the manufacturer's current datasheet to confirm exact frequency tolerance and temperature stability ratings. Ensure the ordering documentation matches the required load capacitance of 7pF and ESR limits. Cross-reference the package dimensions with PCB footprints to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when board area is limited and a 26 MHz reference is required for short-range wireless protocols. The 7pF load capacitance dictates specific external capacitor values for circuit tuning. Confirm that the host microcontroller supports the fundamental mode and can drive the 80 Ohm ESR limit without excessive power consumption.

Part Context

This part belongs to the NX2016 series, a line of miniature crystals engineered for modern portable electronics. The series prioritizes miniaturization while maintaining frequency stability for digital signal processing. The 26 MHz variant specifically targets sub-GHz and Bluetooth ISM band applications where precise timing is critical for data integrity.

Replacement Considerations

Direct substitutes must match the 2.0x1.6mm package, 26 MHz frequency, 7pF load capacitance, and ≤80 Ohm ESR. Verify that alternative manufacturers offer identical fundamental mode characteristics and thermal stability profiles to ensure RF compliance.
