NX2016AB-26MHZ SB2

Overview

The NDK NX2016AB-26MHZ SB2 is a surface-mount crystal oscillator with a nominal frequency of 26.000 MHz. It utilizes the compact NX2016AB package, measuring 2.0 mm x 1.6 mm x 0.50 mm. The device operates in fundamental mode and features a load capacitance (CL) of 7 pF. Frequency tolerance is specified at ±15 ppm at 25°C, with a frequency stability of ±15 ppm across the operating temperature range. The equivalent series resistance (ESR) is 80 Ohms maximum. This component is designed for space-constrained applications requiring precise timing.

Feature Summary

• Compact NX2016AB footprint suitable for miniaturized electronics
• Fundamental oscillation mode operation
• Low profile construction for thin devices

Applications

• Bluetooth Low Energy (BLE) modules
• Wireless LAN interfaces
• Portable IoT sensor nodes
• Wearable electronic devices

Procurement Notes

Verify the specific suffix 'SB2' against the manufacturer's current datasheet to confirm exact packaging and tape-and-reel specifications. Ensure the load capacitance requirement of the host microcontroller matches the 7 pF specification to maintain frequency accuracy. Confirm that the 80 Ohm ESR limit aligns with the oscillator circuit drive level capabilities of the target system design.

Selection Notes

Select this part when board area is limited due to its 2.0x1.6mm dimensions. The 26 MHz frequency is standard for Bluetooth basebands. The 7 pF load capacitance requires careful PCB layout calculation to account for stray capacitance. Verify that the ±15 ppm stability meets the system's total frequency budget requirements under all operating conditions.

Part Context

This component belongs to the NDK NX2016 series, a line of ultra-small crystals designed for modern consumer electronics. The series replaces larger 3225 or 2012 packages to support the trend toward smaller form factors in mobile and wearable technology. The NX2016AB variant specifically denotes the 2.0x1.6mm outline.

Replacement Considerations

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