Yes, a fuse is considered a passive component. It doesn’t have any active function like a transistor or an integrated circuit, meaning it doesn’t amplify, switch, or control signals. Instead, a fuse works purely in terms of its physical property: it is designed to break (blow) when the current passing through it exceeds a certain level, protecting the circuit from overcurrent. It doesn't require any external energy to operate other than the current flowing through it, which is a characteristic of passive components.
So, in summary, a fuse is a simple, non-electrically active component that responds to current conditions, making it a passive element.
