摘要： A chip resistor includes an insulating substrate, a first electrode, a second electrode, a resistor, a first heat transfer layer, a second heat transfer layer, and an insulating protective layer. The first heat transfer layer has a thermal conductivity greater than that of the insulating protective layer, and is in contact with the resistor and a first front electrode. The second heat transfer layer is separated from the first heat transfer layer. The second heat transfer layer has a thermal conductivity greater than that of the insulating protective layer, and is in contact with the resistor and a second front electrode.

摘要： A vehicle, such as a rail vehicle, has an electrodynamic braking apparatus with at least one brake resistor. The at least one brake resistor forms a portion of the vehicle body shell that is permanently closed and over which air flows on the exterior, in particular, during travel of the vehicle. In the alternative, the brake resistor is arranged in the immediate vicinity of the permanently closed portion. The brake resistor conducts away heat outwardly to the environment via the permanently closed portion. There is also described a brake resistor for a vehicle, in particular for a rail vehicle, which is configured accordingly.

摘要： Metal thermal grounds are used for dissipating heat from integrated-circuit resistors. The resistors may be formed using a front end of line layer, for example, a titanium-nitride layer. A metal region (e.g., in a first metal layer) is located over the resistors to form a heat sink. An area of thermal posts connected to the metal region is also located over the resistor. The metal region can be connected to the substrate of the integrated circuit to provide a low impedance thermal path out of the integrated circuit.
