A passive component is an electronic component that does not require a source of energy to perform its intended function. Examples of passive components include resistors, capacitors, and inductors. The classic crystal radio receiver, an AM radio receiver that does not require any electricity, is made entirely from passive components. An electronic component is a basic electronic building block packaged in a discrete form with two or more connecting leads or metallic pads. ... Resistor symbols (US and Japan) Resistor symbols (Europe) A pack of resistors A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in accordance with Ohms law. ... A capacitor is a device that stores energy in the electric field created between a pair of conductors on which electric charges of equal magnitude, but opposite sign, have been placed. ... An inductor is a passive electrical device employed in electrical circuits for its property of inductance. ... The crystal radio receiver (also known as a crystal set) is a passive radio receiver consisting of a variable LC circuit tuned circuit, a diode detector, and audio transducer. ... Mediumwave radio transmissions (sometimes called Medium frequency or MF) are those between the frequencies of 300 kHz and 3000 kHz. ... Lightning strikes during a night-time thunderstorm. ...
A passive filter is an electronic filter made entirely from passive components. Electronic filters are electronic circuits which perform signal processing functions. ...
Compare to active component, an electronic device that requires a source of energy to perform its intended function. In electronics, an active component is one that has gain or depends on the direction of the current. ...
These components can be grouped into arrays with two to six capacitors joined either side-by-side or stacked to eliminate the space between components on the board.
When the components are combined into an array, they have the same total component area as the discrete elements did, but the mounting pad areas are reduced and the clearance areas around each component are eliminated.
Passivecomponent integration is and will continue to be an important contribution in the development of increasingly smaller medical electronics.
Component structures and processes are tailored to ensure acceptable voltage breakdown strengths, generally guaranteeing a minimum value of 50V DC.
Component accuracies for resistor and capacitors in an integrated passive process are a function of layer thickness control limits and feature dimensional accuracy, and they vary with absolute component dimensions.
While laser-based integrated passivecomponent trimming is possible, the freedom to exchange components in the type of board level, iterative design route adopted for SMT products is not practical.
