Fémrétegellenállások
Fémrétegellenállások, also known as metal film resistors, are a type of electrical resistor made by depositing a thin film of metal oxide or metal onto a ceramic substrate. This metal film is then precisely trimmed, typically by laser, to achieve the desired resistance value. They are widely used in electronic circuits due to their good performance characteristics and cost-effectiveness.
The resistance value of a fémrétegellenállás is determined by the thickness and composition of the metal film,
Key advantages of fémrétegellenállások include their excellent stability over time and temperature, low noise generation, and
