Abstract: A chip resistor includes a resistor main body, an insulating layer, a heat dissipating layer, and two electrodes. The resistor main body is formed with plural longitudinally extending slits arranged and spaced apart from one another. The resistor main body has transversely opposite ends connected electrically and respectively to the electrodes. The heat dissipating layer dissipates heat generated by the resistor main body and is formed with a dividing slot extending across one of the slits and dividing the heat dissipating layer into two transversely spaced-apart portions. The insulating layer is sandwiched between the resistor main body and the heat dissipating layer and electrically insulates the heat dissipating layer from the resistor main body.

Abstract: In a method of manufacturing a chip resistor, a semi-product is formed by sandwiching an electric-insulating material layer between an electric-conducting material layer and a heat-dissipating material layer. Resistor sections arranged in an array on the semi-product are formed by forming longitudinal first slots and transverse second slots through the semi-product. Slits are formed on a first layer of each resistor section to form a resistor main body. A dividing slot is formed on a second layer of each resistor section. Two electrodes are formed to be electrically connected to opposite ends of the resistor main body. The resistor sections are trimmed from the semi-product to obtain the chip resistors.

Abstract: A thin-film inductor device includes a substrate made of an electrically insulating material, a first coil unit, a second coil unit, and an inductance-enhancing structure. The first coil unit includes a first upper coil, a first lower coil, and two first electrodes electrically connected to the first upper and lower coils, respectively.
