Passive components, like resistors, are hard to be chosen as the regulations and the unique characteristics of the healthcare environment. Since the human body is intrinsically analog, though, there will always be an important role for highly reliable passive components, like resistor, in systems including diagnostic, imaging, patient monitoring, instrumentation, and pharmaceutical delivery and dispensing applications. Approximately 20 passive components, resistor for example, are needed for each active IC in a design. AEDs p...

Shunt resistors is primarily used to measure current. However, the meaning of the term shunt in electronics is broader than that. A shunt is an element that is used in a circuit to redirect current around another part. The areas of application vary widely. For some applications, electrical devices other than resistors can be used. A few examples are given to illustrate the diversity of shunts. Several parameters are important to specify a shunt resistor. Shunt resistors have a maximum current rating. The resistance value is g...

High-voltage resistors are used for office equipment and home appliances such as printers, copying machines, and air-conditioners. Offering high resistance and small deviation values, Microhms products enable reduced set circuit signal inconsistencies and more reliable final products. One of the role of resistors in a circuit is detecting high voltage by voltage dividing. Rated voltage and maximum working voltage are specified for each resistor, which should not be exceeded when it is used. Plural resistors have to be used in...

Inverter power resistor applications probably require filter resistors, gate resistors, snubbers, balancing resistors, bleeders, voltage dividers, braking/regenerative braking resistors, power factor control, pre-charge resistors, surge current protection, and even current shunts. Here we discuss the various resistor solutions. Microhms expansive line of wire wound resistors work exceptionally well for use in the high energy locations in the diagram such as braking and surge current protection. The NUAL series offers high po...

A wirewound resistor is an electrical passive device that limits or restricts current flow in a circuit. Wirewound resistors are constructed using a conductive wire. The conductive wire is then wound around a non-conductive core. The conductive wire can be made of varying alloys and thickness to control the resistance value. Microhm offer over different series in wirewound construction. which can be chosen based on mounting, application, and resistance range. Different types of wirewound resistors include Precision, Axial, Tu...

Voltages above maximum applied voltage may cause an arc between the resistor terminals. At high voltages, RP can also become significant, allowing current to leak around the internal resistance. High-voltage resistors must be kept clean. Fingerprints, oil, dirt, and dust all create unwanted current paths, lowering RP and increasing leakage or even arcing. This is why resistors for use in high-voltage circuits are long and thin with their terminals far apart to minimize leakage and maximize the ability to withstand high voltag...

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...
