electronica China, lasting for three days, ringed down the curtain on Mar.22,2019 successfully. Microhm prepared elaborately and exhibited full range of resistors in the site. Customers from all over the world visited Microhm E5 - 5606, consulted resistors and experienced. Our staffs introductions of the features, applications and merits were brief and to the point. Customers not only stayed for a time in front of the reception to learn more about products, but also streamed into Microhms booth to have a close look of the mat...

High Value Resistors with specified properties at small sizes. To analyze very low electronic signals, resistors with extremely high values are required. Microhm has succeeded in producing such components with stability better than the best measuring devices available on the market. It is possible to achieve also at very small sizes like 0402 (10.5mm) resistance values close to the range of insulators with specified properties for temperature and voltage dependency. Resistor pastes for the high value range are much more sens...

To mount extremely small components accurately require accurate , stable product shape, designing substrate as well as high precision printing technology of cream solder and mounting technology. Carrier tape precision is also required. In the interest of achieving higher voltage and reliability, resistive material itself needs improvement. The movement of Pb-free is required now not to use Pb-contained solder for electrode plating of resistors. In the future, every one of material such as resistor film, protective film and in...

In a film resistor, the resistive material is a very thin coating of carbon ,metal or metal oxide on an insulating substrate, such as ceramic or glass. The value of the resistance is determined by the thickness of the film and the amount of carbon or metal in it. These resistors are available with very accurate and stable values. Apart from shunt resistor, surface-mount resistors are almost always film resistors. These resistors have no leads at all, so LS is very low. The film is deposited on a ceramic sheet. Because of the...

Resistors are passive component applicable to various applications, for instance, smartphones, CPU power supplies and LCD projectors. To achieve power management performance of portal devices, high precision measurement of current is required. To measure the circuit current in general, first you insert current sense resistors in serial into a circuit then measure each voltage of both ends of the resistor. Like smartphones, however, when the current gap happens to be more than a hundred times between standby and operating APs,...

Power resistor market are focusing on developing power resistors that dissipate huge amount of power, while keeping their size as small as possible. In an electric circuit, power resistors endure and distribute a huge amount of power. This power dissipation by a power resistor results in accelerated increase in temperature, after which the power resistor starts dissipating power through the circuit board and the surrounding atmosphere. In order to minimize this kind of dissipation and the consequential hazardous failure condi...

The foil resistor is the high accurate and stable component used to restrict the electric current flow to certain level. The foil of this resistor is made from an alloy which is of nickel, chromium, and additives are used to construct the foil because these materials provide high resistance to electric current and protect the foil resistor from damage. In the recent years, the demand for high accurate, stable and reliable devices that operates in harsh environments has increased. Many industries, automotive, medical, military...

The metal film resistors are more preferred over carbon composition resistors because the metal film resistors generate less noise than the carbon composition resistors. While the metal film resistors have low tolerance value than the carbon composition resistors. In metal film resistor, the desired resistance value can be achieved by either trimming the thickness of metal layer or by cutting the metal film in a helical manner along its length. This is generally done by using the lasers. Once the desired resistance value is o...

Resistors are available in a large amount of different packages. Nowadays the most used are the rectangular surface mount resistors, which mainly consist of thin film resistors and thick film resistors. Thin film resistors and thick film resistors are characterized by a resistive layer on a ceramic base. Although their appearance might be very similar, their properties and manufacturing process are very different. The naming originates from the different layer thicknesses. Thin film has a thickness in the order of 0.1 microme...
