NX2016AB-40MHZ SW2W

Overview

The NDK NX2016AB-40MHZ SW2W is a surface-mount crystal oscillator designed for wireless LAN applications. It features a compact 2016 (2.0mm x 1.6mm) package with a height of 0.50mm. The device operates at a nominal frequency of 40MHz using fundamental mode oscillation, eliminating the need for overtone suppression circuits. Key electrical specifications include a maximum equivalent series resistance (ESR) of 60Ω and a specified load capacitance (CL) of 7pF. Frequency stability is maintained within ±20ppm tolerance at 25°C and across the full operating temperature range of -30°C to +75°C. The component utilizes a four-terminal SMD configuration without leads.

Feature Summary

• Fundamental mode oscillation design simplifies circuit matching by removing requirements for overtone suppression components.
• Compact 2016 package dimensions optimize PCB space utilization for miniaturized wireless devices.
• Integrated thermal stability ensures consistent frequency performance across industrial-grade temperature ranges.

Applications

• Wireless LAN modules requiring precise clock references
• Miniaturized consumer electronic devices with strict size constraints
• Industrial wireless communication equipment

Procurement Notes

Verify that the ordering suffix matches the required load capacitance and frequency tolerance specifications. Confirm the manufacturing date code to ensure material freshness, as aging can affect long-term frequency stability. Ensure the procurement channel provides original manufacturer documentation to validate authenticity against counterfeit components.

Selection Notes

Select this component when board space is limited and fundamental mode operation is preferred to reduce BOM complexity. Ensure the host IC's drive level capability aligns with the 60Ω ESR limit to prevent overdriving. Verify that the system's frequency accuracy requirements fall within the ±20ppm specification across the intended operating temperature range.

Part Context

This part belongs to the NX2016AB series, which is engineered specifically for high-frequency stability in small form factors. The series targets short-range wireless technologies where size reduction and signal integrity are critical. It serves as a direct replacement for larger 3225 packages in space-constrained designs.

Replacement Considerations

Direct substitutes must match the 2016 footprint, 40MHz frequency, 7pF load capacitance, and ±20ppm stability. Verify pin compatibility and ESR limits before integration. Cross-reference with other manufacturers' 2016 series crystals ensuring identical electrical parameters.
