LED technology is becoming an increasingly popular choice for lighting up the headlights of modern cars as well as their displays and cockpits. Special resistors, from resistor manufacture such as Microhm Electronics, are necessary to make the diodes work properly. LED (light emitting diode) technology provides automotive suppliers with a challenge: The rear part of the light unit leaves only little space for installation and the law requires a minimum brightness level. On top of that, LED chains must not emit different brigh...

South America is often known as the continent of extremes, it is home to both the worlds greatest river and the driest desert. Its geographic variations include the snow-capped Andes, tropical jungle, savannah-style grasslands, the mighty Amazon and Orinoco river deltas and coastal plains. This extreme geography has resulted in the formation of isolated communities, which means that power distribution can be piecemeal in nature. This kind of geography and climate affects the resistor market. Remote conditions The power needs...

In recent years, renewable energy options have become much more efficient and feasible. Just like all other power generation methods, these applications require resistors, like high power resistors, high precison resistors. Renewable technologies are reaching a level of maturity where they are heavily impacting many nations energy mixes. Although embracing renewables is great for the environment, it does face its own set of challenges. Each source of renewable energy is dependent on the environment around it, meaning that pr...

Medical devices are leaving the confines of hospitals and serving the growing community-based and home-based healthcare markets. In particular, analysts cite the need for faster, lower-power, higher-precision, and more intelligent electronic devices. Since the human body is intrinsically analog, though, there will always be an important role for highly reliable passive components in systems including diagnostic, imaging, patient monitoring, instrumentation, and pharmaceutical delivery and dispensing applications. Approximatel...

Shunt resistors are a popular current-sensing sensor because of their low cost and good accuracy.Microhm Electronics shunt resistor MMS2512, MMS3920 to MMS8420 are applicable to this function. The voltage drop across a known low value resistor is monitored in order to determine the current flowing through the load. If the resistor is small in magnitude, the voltage drop will be small and the measurement will not have a major effect on the motor circuit. The selection criteria of a shunt current resistor requires the evaluatio...

Power resistors are used in power generation and distribution, high-voltage applications, control systems, and other power system applications. They include load banks, grounding resistors, and dynamic braking resistors. Load banks develop an electrical load, apply the dummy load to an electrical power source, and then convert or dissipate the resulting power output. Load banks are used to test generators, uninterruptible power supplies (UPS), and other backup generation systems. Grounding resistors or neutral earthing resist...

Microhm Electronics metal current sense resistors are popular devices used to measure current flow. When evaluating these products for a given application, designers will need to test their resistance value. To be assured of obtaining a correct reading when testing the resistance, it is important to employ the proper test method for the most accurate results. Resistance value measurement tests typically use standard multimeters with two measuring wires. This measurement method is suitable for resistance values higher than 10 ...

What is a TO Package? The increase of power capabilities for transistor technology lead to the development of device packages capable of dissipating much greater amounts of heat. These specialized packages are referred to as transistor outline, or TO package. The high-power versions of these packages have been adopted by other types of components as a convenient way to enhance thermal performance. TO packages for resistors. The most common packages utilized by resistor manufacturers are (in order of power capabilities) the T...
