Resistors

A resistor is a passive electrical component with two terminals that serves as an element in a circuit by providing electrical resistance. In electronic circuits, resistors fulfill various functions, including limiting current flow, adjusting signal amplitudes, dividing voltages, biasing active components, and terminating transmission lines. They are also employed in high-power applications where they dissipate significant electrical power as heat, such as in motor control systems, power distribution networks, or as load components for generator testing. Fixed resistors exhibit minimal changes in resistance due to temperature, time, or operating voltage variations. On the other hand, variable resistors, often referred to as potentiometers, are employed to adjust circuit parameters, such as volume control or lamp dimming. Additionally, they find use as sensors for measuring environmental factors like heat, light, humidity, force, or chemical activity. TECHDesign offers Walsin and PDC resistors in Thick Film series, Thin Film series, and Metal series. View less
