What is 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 chip resistor array?
Samsung Electro-Mechanics manufactures highly reliable, ultra-small SMD resistors and arrays. Chip resistors are passive components which are useful for reducing voltage and controlling currents.
What is the difference between thick and thin 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, which is a mixture of glass and metal oxides, onto the substrate. Thin film is more accurate, has a better temperature coefficient and is more stable.
What are thin film resistors made of?
Thin film resistors are built on a ceramic base, with the resistive layer sputtered on top using vacuum deposition to create a chip resistor. The material used is commonly an alloy of nickel and chrome called Nichrome.
What is thick film and thin film?
Thin film has a thickness in the order of 0.1 um (micrometer) or smaller, while thick film is thousands times thicker. However, the main difference is the method used to apply the resistive film onto the substrate. Thin film resistors have a metallic film that is vacuum deposited on an insulating substrate.
Where is a thin film resistor used?
Thin Film resistors are typically used for applications that require high stability, high accuracy, or low noise. Such applications may include test and measurement equipment, monitoring equipment, medical equipment, audio applications, precision controls and instrumentation.
Why are thin films used?
Thin films are generally used to improve the surface properties of solids. Transmission, reflection, absorption, hardness, abrasion resistance, corrosion, permeation and electrical behaviour are only some of the properties of a bulk material surface that can be improved by using a thin film.
What are thin film circuits?
Thin-film technology uses semiconductor and microsystem technology processes to produce circuit boards on ceramic or organic materials.
