A zero-ohm resistor is a resistor that has almost no resistance at all; its resistance is near 0 ohms. A zero-ohm resistor can be wire wound or it can be surface mount. For wire wound resistors, there will be a single black color band around the body of the resistor. For surface mount resistors, there will be a 0 on it indicating it is a zero-ohm resistor. LMK series of Microhm Electronics include zero-ohm resistors, the actual value is less than 0.05m, rated current ranges from 0.5A to 2.5A. Zero-ohm resistors are available ...

In metrological applications, where accuracy is of paramount importance, highly precise standard resistors are also equipped with four terminals: two for carrying the measured current, and two for conveying the resistors voltage drop to the voltmeter. This way, the voltmeter only measures voltage dropped across the precision resistance itself, without any stray voltages dropped across current-carrying wires or wire-to-terminal connection resistances. Microhm Electronicss MVR2321-4, shunt resistor MMS4026 are typical and popul...

Power management has evolved as electronics continually are miniaturized and deployed in an increasing array of applications. Since there are so many types of specialized circuits with unique operating voltages, it has become commonplace to provide a single external voltage level to a device and to rely on conversion within the device to provide the appropriate power levels to each load. For example, a device may have nine loads and require five voltages, which can be provided by incorporating DC-DC converters. Microhm Elect...

Renewable power is not a recent phenomenon. Hydroelectric plants have been popular in some areas for many decades. Power from these renewable sources differs from conventional sources, such as coal, gas, and nuclear plants. This is because renewables either generate dc power directly, or the power they generate requires some conversion between ac and dc and back. Carbon-based generation inherently produces ac power, which can easily be fed into the grid using substation transformers. As an important passive component, resisto...

Resistors are seemingly the most mundane of components. The conventional wisdom is that their tolerances are poor; their values change over temperature; they have significant capacitance and inductance; and They cost fractions of a cent in high volume. But what if you need highly precise parts that maintain their performance over a wide range of environmental and electrical conditions? For precision use, several technologies - thick film, thin film, foil, and wirewound - are available, offering tradeoffs in performance versus...

Keeping your car or truck at the temperature you desire is a crucial element of your driving comfort. When something goes wrong and you cant cool off in the summer, or get warm in the winter, it can make every drive into an uncomfortable trip. A car which is not maintaining temperatures properly may be suffering from a blown blower motor resistor. If your car is in need of a new resistor, you want to shop from among the best blower motor resistors for cars and trucks to find the ideal option for you. There are many warning si...

Resistors are present everywhere in our life. All electronic boards and devices utilize them. Our laptop boards, mobile phone, juicer machine circuits, home accessories all contain SMD resistors. They are used in kettles, lamps, geezers, speakers, headphones and almost all electronic/electrical devices. MICROHM Electronics resistors are often seen in these areas. Below are the top 5 practical applications of resistors in our daily life. Mobile phone charger Just like the laptop, a mobile phone charger contains a number of res...
