vastagfilmellenállás

Vastagfilmellenállás translates from Hungarian to "thick-film resistor." This is a type of electronic component used to resist the flow of electric current. Thick-film resistors are manufactured by screen printing a resistive paste onto a substrate, typically ceramic. This paste is composed of a mixture of conductive particles, insulating binders, and a solvent. After printing, the resistive layer is fired at high temperatures, causing the binder to fuse and create a durable, continuous resistive element.

The thickness of this printed film is significantly greater than that of thin-film resistors, hence the name "thick-film." This manufacturing process allows for the creation of resistors with a wide range of resistance values and power ratings. They are generally less precise than thin-film resistors but are more cost-effective for applications where high precision is not critical. Common applications include power supplies, consumer electronics, and automotive components. The resistive material can be varied to achieve different resistance characteristics. The exact composition of the resistive paste determines the final resistance and its temperature coefficient.
