This document describes the features and characteristics of the 8431 series thin film ceramic chip inductors, including tight tolerance of 2% or 0.2nH, self-resonant frequency controlled within 10%, stable inductance in high frequency circuits, and compatibility with either reflow or flow soldering.
The 8431 Series thin‑film ceramic chip inductors are designed for high‑frequency applications such as cellular phones, GPS, wireless LAN, VCO, and TCXO circuits. They provide a tight 2 % tolerance, stable inductance across a wide range, and are compatible with RF transceiver modules.
Electrical specifications include inductance values from 1.0 nH up to 68 nH (0803 size) or 22 nH (0402 size), a self‑resonant frequency controlled within 10 %, and a tolerance code G = 42 %. Environmental tests cover bending, vibration, solder‑heat resistance, temperature cycling, moisture, and low‑temperature storage, ensuring reliable performance in harsh conditions.
