Resistors are tend to be high precision, high reliability, high voltage, PB free as well as high density mounting. Narrow space mounting is achieved by fillet-less mounting to improve mounting density. As the requirements for higher performance in the restricted space are increasing, not only a resistor but resistor network will need downsizing and area array mounting. The recent market requires higher density mounting, which leads to the request for higher power at conventional product size. Resistors had been used with luxu...

Resistors, like many electronic components, come in a variety of types, shapes, sizes, capacities, and each has significant differences in typical values for resistor wattage rating, tolerances, temperature coefficient, noise, voltage coefficient, frequency response, size, and reliability. Film resistors are most used ones in circuits and consist of carbon composition resistors, carbon film resistors, thick film resistors, thin film resistors and metal film resistors. Take the last two for instance. Borrowing from semiconduct...

Microhm Electronics announced a surface-mount metal foil current sensing resistor designed to save space in automotive, industrial, computer, and consumer applications. The NMS2818 combines a high 5 W power rating with extremely low resistance values down to 4 mR in the compact 2818 case size. The advanced construction of the NMS2818 resistor incorporates improved thermal management and a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR. This results in a high-power resistor in the 2818 packa...

Array resistors are made from a combination of several resistors that are configured into a pattern, one single array resistor can replace four or two single resistors. . Although most array resistors use resistors connected in series, some array resistors use resistors in parallel or series-parallel designs. The resistors in a network act as voltage dividers which divide the voltage that is applied to a circuit into smaller amounts. Resistor arrays are a type of fixed resistors devices which are used in electrical circuits t...

Power resistors wattage rating is specified at a temperature of 25C. As the temperature of a power resistor climbs above 25C, the power that the resistor can handle safety begins to drop. Since 25C is a typical room temperature, and any power dissipated by a power resistor generates heat, running a power resistor at its rated power level is often very difficult. To adjust for the expected operating conditions, manufacturers provide a derating chart which shows how much power the resistor can handle as the temperature of the r...

Resistor is an element that converts electric energy into heat energy. It always generates heat when the electric power is consumed and the temperature rises according to the consumed power. To control the temperature rise of a resistor, the generated heat needs to be dissipated efficiently. Some power resistors of Microhm improve the heat radiation by adding heat sink. For chip resistors, the most of the generated heat conducted from the electrode to Cu foil pattern, and finally dissipated to the air or chassis. Temperature ...

Microhm, a specialist manufacturer of shunt resistors and precision resistors, announced to broaden its extensive line of high-power wirewound resistors, with a new series of rugged metal-clad wire wound resistors that deliver high levels of performance and a reduction in the need for heatsinking. They are also significantly less sensitive to heatsink requirements than a comparable TO-packaged device of a similar power rating, many of which may require a cold plate to operate at the same rated power. The LHR series high level...
