Passive components
What are passive components?
A passive component is a component that does not generate power or require an external power source to operate. Instead, it either stores energy or dissipates energy in the form of heat or electromagnetic fields. Unlike active components (such as transistors or integrated circuits), passive components do not have the ability to amplify signals or control current directly.
Express Electronics have 10,000 products in stock and access to hundreds of thousands more, so we can find the passive components you need no matter how specialised the purpose.
Types of passive components
- Capacitors: A capacitor is a small electronic component that stores electrical energy. It does this by holding the energy between two metal plates separated by an insulating material. Capacitors are used in many devices such as fans, lights, and electronics.
- Inductors: An inductor stores energy as a magnetic field and can release that energy back into the circuit when needed. Inductors are commonly used to manage energy flow in various electrical devices.
- Resistors: Rather than storing energy, a resistor slows down the flow of electrical current by converting electrical energy into heat. Resistors are found in things like electric heaters, toasters, and ovens.
- Transformers: Transformers are devices that change the voltage levels in an electrical circuit. Even though they change the voltage, they don’t add or lose energy. Transformers are widely used in power stations, household appliances, and lighting systems.
- Diodes: Diodes are tiny components that control the direction of electrical current in a circuit. They ensure that electricity flows in only one direction, making them essential for converting AC to DC and for other signal processing tasks.
