What are thick film resistors used for?
Such applications may include test and measurement equipment, monitoring equipment, medical equipment, audio applications, precision controls and instrumentation. Thick film resistors are used on literally every type of electrical device; if it has a battery or an AC plug, it will probably have a thick film resistor.
What’s the difference between thin film and thick film resistors?
Thin film resistors have a metallic film that is vacuum deposited on an insulating substrate. Thick film resistors are produced by firing a special paste onto the substrate. Thin film is more accurate, has a better temperature coefficient and is more stable.
Are thick film resistors inductive?
Thick Film Construction and Properties Thick film resistors offer high resistance values, up to 10TW (tera-ohm), very high-temperature performance and high voltage capability and are inherently non-inductive. Thick film resistors are made by silk-screening conductive paste onto an insulating substrate (see figure 5).
What type of resistor is best for high power applications?
For very high-power applications, such as dynamic braking, nichrome wire resistors are ideal, especially when the load is expected to be hundreds or thousands of watts. Nichrome wire resistors can also be used as heating elements. Common types of resistors include: Wirewound resistors.
How can you distinguish thin film with thick film?
Thin film has a thickness of 0.1 micrometer or smaller, while thick film is around thousands time thicker than thin film. The main difference is method of applying resistive film onto the substrate. Thin film resistors have a metallic film that is vacuum deposited on an insulating substrate.
What is a power film resistor?
Power resistors are designed to withstand and dissipate large amounts of power. Power resistors are made from materials with a high thermal conductivity, allowing efficient cooling. They are also often designed to be coupled with heat sinks to be able to dissipate the high amounts of power.
What are 3 types of resistors?

What is a thin film resistor?
Thin film resistors are a type of resistor that possess a thin resistive layer sat on top of a ceramic base. The principle difference between thick and thin film resistors is the thickness of this resistive layer, with thin films possessing a thickness of around 0.1 microns.
What is a thick film?
thick film. n. A thick, engineered layer of material deposited on a substrate with a thickness typically measured in micrometers , used in electronic and optical applications.
What is a thick film circuit?
thick-film circuit. A microcircuit in which passive components, of a ceramic-metal composition, are formed on a ceramic substrate by successive screen-printing and firing processes, and discrete active elements are attached separately.
What is a film resistor?
film resistor. A fixed resistor in which the resistance element is a thin layer of conductive material on an insulated form; the conductive material does not contain binders or insulating material.
