1. Passive Components is the terminology used within the electronics industry in Taiwan to refer to a specific
category of electronic components, distinct from Active Components. In mainland China, these are referred to as
“passive devices” and “active devices,” respectively. Currently, domestic industry practice generally follows the
terminology of “passive components” (resistors, capacitors, inductors) and “active components” (integrated
circuits). If an electronic component operates without any internal power source, it is classified as a passive
device. These primarily include: resistors, capacitors, inductors, ceramic resonators, crystal oscillators, and
transformers.
2. Active Components (or Active Devices) generally refer to devices that require energy to perform their specific
functions. If an electronic component operates with an internal power source present, it is classified as an active
device. These primarily include: (1) Electron Tubes (also known as vacuum tubes)—the earliest form of active
electronic components—which are categorized into diodes, triodes, and multi-electrode tubes; (2) Transistors—
electronic devices fabricated using crystalline materials such as silicon or germanium (classified as semiconductor
materials)—which are categorized into semiconductor diodes and semiconductor triodes; and (3) Integrated
Circuits (abbreviated as IC; also referred to as microcircuits, microchips, or simply “chips”).
