MetalloxidWiderstände

MetalloxidWiderstände, also known as metal oxide film resistors, are a type of passive electronic component that provides electrical resistance. They are constructed by depositing a metal oxide layer onto a ceramic substrate. This metal oxide layer, often tin oxide or a mixture of metal oxides, forms the resistive element. The resistance value is determined by the thickness and composition of this oxide layer, as well as the geometry of the resistive track.

These resistors are known for their good stability over time and temperature. They can withstand higher temperatures and exhibit better surge handling capabilities compared to some other resistor types, like carbon composition resistors. The manufacturing process typically involves heating the ceramic substrate in a furnace with the metal oxide material, allowing the oxide to form a thin, uniform film. A helical groove is often cut into the resistive layer to precisely adjust the resistance value.

MetalloxidWiderstände find applications in various electronic circuits where reliability and stable performance are important. They are commonly used in power supplies, motor control circuits, and general-purpose resistance applications. Their robust nature makes them suitable for environments that might subject components to thermal stress. While they offer good performance, they may have limitations in terms of precision compared to some other resistor technologies.
