Solution Overview

Problem

Existing composite electronic components with integrated resistor and capacitor elements face limitations in design freedom due to constraints in processing difficulty, electrical characteristics, and circuit configuration, primarily because the resistor body is formed directly on the capacitor body or requires identical shapes and dimensions for the components, limiting their use in various circuits.

Innovation Solution

A composite electronic component design featuring a resistor device with an insulating base and a capacitor device mounted in a heightwise direction, where the resistor body is positioned between conductive layers on the insulating base, allowing for independent electrical connections and flexible design without the need for identical shapes or dimensions, enabling increased design and manufacturing freedom.
