Abstract
(EN)
A metal foil resistor having a metal foil resistive element (20) composed of a metal foil whereupon a resistor circuit pattern is formed. The metal foil resistor is provided with a package (10) which stores the metal foil resistive element (20) in an insulated state to have the resistive element to extend and retract in a spreading direction; and an external terminal (26) which is held in the package (10) in an insulated state and is connected to an electrode section (20a) of the metal foil resistive element (20). The resistor temperature coefficient can be reduced and stabilized, and degrees in freedom in designing can be increased by reducing adjusting elements. Furthermore, the package is easily attached to a discretionary heat sink by preventing external stress applied to the package from transmitting to the metal foil resistive element.

La présente invention a trait à une résistance à film métallique comportant un élément résistif de film métallique (20) constitué d'un film métallique permettant la formation d'un motif de circuit de résistance. Le film métallique est muni d'un boîtier (10) qui renferme l'élément résistif de film métallique (20) dans un état isolé pour permettre à l'élément résistif de se déployer et de se contracter dans une direction d'étalement; et une borne extérieure (26) qui est contenue dans le boîtier (10) dans un état isolé et est reliée à une section d'électrode (20a) de l'élément résistif de film métallique (20). Le coefficient de la température de la résistance peut être réduit et stabilisé et de degrés de liberté dans sa conception peuvent être accrus par la réduction d'éléments d'ajustement. En outre, le boîtier peut facilement être fixé à un drain thermique en interdisant la transmission de l'application d'une contrainte extérieure au boîtier à l'élément résistif de film métallique.
