FAQ

A type of resistor made from winding a metal wire, such as nichrome, on an insulating form, such as a ceramic, plastic, or fiberglass core.

A type of cylindrical resistors made by depositing a resistive element made of a thin conducting film of a metal or metal alloy, such as nichrome, onto a cylindrical ceramic or glass core. The resistance is controlled by cutting a helical groove through the conducting film.

A type of cylindrical resistor that uses materials such as ruthenium oxide or tin oxide as the resistive element. These resistors can be excellent high-voltage or high-power devices.

Specially built surface-mount film resistor that carries high power for the part size. For thick film resistors, the ruthenium oxide “film” is applied using traditional screen-printing technology.

A type of surface-mount film resistor with a relatively thin resistive element, measured in angstroms (millionths of an inch). Thin film resistors are made by sputtering (also known as vacuum deposition) a resistive material, such as nichrome or tantalum nitride, onto the surface of a substrate.

A general class description for cylindrical resistors made by depositing a carbon film on the surface of a center core insulator.

A general class description for resistors consisting of a carbon mixture resistive core and a molded outer insulating core.

A type of resistor constructed using a solid metal alloy, such as nichrome or manganesecopper, as the resistive element, which is then welded to copper terminals. Used in current sense and shunt applications.
