4 Terminal Kelvin Resistors

4 Terminal Kelvin Resistors

A Kelvin configuration resistor features four leads or terminations. These four terminal resistors enable current to be applied through two opposite leads and a sensing voltage to be measured across the other two leads. The Kelvin configuration effectively eliminates the resistance and temperature coefficient of the leads. The Kelvin connection can also simplify board design by incorporating all terminals for the sensing circuit into one part. A Kelvin connection is essential for accurate current sensing and simplified board ...

Current Sensing Resistors Working Principle

Current Sensing Resistors Working Principle

Current sensing products are established industry favorites among resistive products. A majority of current sense resistors are surface mount, as is true with most passive products. Current sense resistors are often referred to as shunt resistors. Shunt resistors are used to monitor the amount of current that is flowing through a circuit. Such resistors have very low resistance values, typically less than10 milli-ohms (0.010 ohms) and often lower. Microhm milliohm shunt resistor lineup cover size 0603 to 8420 for BMS and more...

Resistors for Wind Turbines  and Tidal Turbines

Resistors for Wind Turbines and Tidal Turbines

Microhm has comprehensive marine experience, and supplied water and air-cooled break and submerged load resistors. Microhm products are designed to withstand adverse marine conditions. For large-scale wind farms where varying wind speeds effect the quality of power an SVC can be fitted to regulate transmission voltage. The SVC can also improve availability by reducing the impact of power fluctuations. Despite being less common than wind or solar power, wave and tidal power has a number of benefits. It is considerably more pr...

Shelf Life of Resistor Products

Shelf Life of Resistor Products

All components shelf life depends on storage conditions and type of packaging. The main concerns with the storage of SMT passive components is humidity content, temperature, and tape Reel degradation which could ultimately affect solderability. Electronic devices are available in many package types and can contain semiconductors, magnets, capacitors, and resistors. Precautions against ESD (electrostatic discharge), moisture, and contaminants need to be considered for electronic devices. The shelf life of resistors is determin...

Resistors' Classification

Resistors' Classification

Resistors are widely used passive component. They are assorted by function, shape, resistive material and its purposes. Categorized by function, resistors are mainly classified to fixed resistor used in a electric circuit and variable resistor used as a radio volume by changing the resistance. Microhms shunts are typical fixed resistors. Fixed resistors are divided into lead type(with lead wire) and surface mount type without lead wire. Surface mount type includes rectangular type, such as Microhm MPR series, NMS series and c...

SMT Resistors' Advantages and Disadvantages

SMT Resistors' Advantages and Disadvantages

Different Types of SMD Resistors divided to chip resistor, MELF, shunt resistor, network resistor, chip jumper and more. When considering the use of SMT resistors there advantages and limitations must be kept in mind. Even though SMT resistors are widely used there are a few points worth remembering: The size and construction of SMT resistors means that they have much lower levels of of stray inductance and capacitance and as a result they can be used for much higher frequency operation. Surface mount resistors are naturally ...
