Testing the capacity and fitness of a generator or power supply before going live is vital to success in the field. Likewise, maintaining the operation of these devices - especially in diesel...

In electronic circuits, resistors are used to limit the amount of current flowing to a circuit, divide voltages, adjust signal levels and terminate transmission lines, among other applications....

When it comes to selecting the right type of resistor for an electronic application, the choices can feel overwhelming. Wirewound resistors and composition resistors are two common options, each with...

Choosing the right EMI filter for any application requires understanding several aspects of the equipment it will be used in. Will the equipment be subjected to extremes in electromagnetic energy,...

All resistors share one property: stresses, whether mechanical or thermal, can cause a resistor to change its electrical parameters. Temperature and power dissipation will cause this stress in...

It’s hard to miss the biggest coming revolution in transportation: electric vehicles. Sports cars, sedans, pickup trucks, semis, heavy equipment in agriculture and construction—even...

Feedback loops are the bread and butter of control systems. To prevent something from spiraling into larger and larger oscillations or spiked values, it's critical to bring them back into normal...

Having to dissipate more than five watts of power in your circuit topology? You need a power resistor. They are important in many applications: power infrastructure, dummy loads, braking systems for...

Operating temperature and thermal performance are directly related; the lower, the better - and the higher a device's reliability. Thermal management is more critical than ever for electronic product...

All resistors dissipate energy and generate some heat. Power resistors differ in the larger amounts of energy they can burn off as heat, through a challenging application of Ohm's law. That requires...

Ceramic resistors offer some great characteristics and capabilities for demanding applications, particularly in high-power circuits. They can handle from 0.5 watts to 1,000 watts in a single component...

A resistor is a device connected into an electrical circuit to introduce a specified resistance. The resistance is measured in ohms. As stated by Ohm’s Law, the current through the resistor will...
