Thin Film Resistor Vs Metal Film

The resistor consists of a thin metal layer on a non conductive material. Thick film and thin film resistors a comparison.

But in general thin films overall thickness is literally thinner because of the subtractive process.

Thin film resistor vs metal film. Thin film or metal film resistors have said film vacuum deposited allowing for a much more uniform and controlled resistive element. The alumina substrate is metalized then a resistive paste is deposited on top of the terminals. Whats the difference between foil and thin film resistors.

The paint is fired to make the assembly permanent. When cost is the only consideration use metal films. The distinction is normally thick film thin film and metal foil in lower of decreasing noise.

The resistive element for thin film resistors is approximately 1000. Endgroup dknguyen feb 24 at 1642. Thick film resistors have many carbon resistor characteristics.

Thin film resistor manufacturers deposit the complete device on a substrate attach leads laser trim to value and encapsulate the. In this case more often the term metal film resistor is used. Even though they look essentially the same to the naked eye and share many of the same process steps thick film and thin film technologies are very different.

It is later trimmed coated metalized on the edges and plated. Now film technology products are replacing carbon resistors. The gap between prior thin film networks and the new generation of foil networks applies primarily to absolute tcr stability and value range.

Metal film resistors are best if the application involves fast rise times microseconds or high frequencies in mega hertz. Widening the gap between precision resistor networks. Thick film resistors are screen printed.

Thin film is definitely not metal foil. Usually thin film is produced as a chip or smd resistor but the film can also be applied onto a cylindrical base with axial leads. The key deciding factor between wirewound or metal film precision resistor technology is depends on the application.

When you say metal film you might actually be meaning to say metal foil. In this case more often the term metal film resistor is used. Metal film resistors are the most common form among thin film resistors.

Metal film resistors are a type of resistors that use a thin metal film to limit the electric current flow. Thick film resistors are made by silk screening conductive paint onto an insulating substrate. There are two common film types thick film and metal or thin film.

Both thick film and thin film resistors are laser trimmed to their final resistance value. Metal foil also has higher temperature stability than the other two. Use metal film resistors.

Keep in mind that thick and thin film resistors are also application specific.
