Technical Specifications:

The 0402HP-3N9XGLW has an inductance of 3.9 nH with a typical tolerance of ±2%. Its high Q factor minimizes losses in RF circuits. The self-resonant frequency (SRF) is typically very high, allowing the inductor to be used at high frequencies. The 0402 package indicates its small size (0.04 inches x 0.02 inches). It features a wirewound construction, contributing to its high Q and stable performance.

This inductor is particularly well-suited for demanding RF applications where low insertion loss and sharp frequency response are essential. Its small size allows it to be used in densely populated circuit boards. The high Q factor ensures efficient energy storage and low dissipation. The tight tolerance guarantees consistent performance across different units, which is critical in precision circuits. The wirewound construction provides superior performance compared to other types of chip inductors.
