Riedon’s PF2272 and PF2274 now feature resistance values up to 1Mohm Advanced manufacturing techniques have allowed Riedon to extend the resistance values available for our two hundred watt (PF2272) and three hundred watt (PF2274) TO-227 packages from 100KΩ to...

Choosing a resistor for pulse applications can be tricky business. What is the magnitude of the pulse? How long does it last? How often does it repeat? What is an acceptable resistance range? And then there are the multiple resistor technologies to consider. A typical...

Heat dissipation is a key factor in the design of a power system; in a world where the trend is for more power in a smaller space, are TO-style packages still the best solution? TO packages were originally intended for discrete transistors, in fact TO stands for...

Maintaining a constant temperature around precision resistors is integral to maintaining the stability of a circuit. Even small fluctuations in the temperature of a resistor can cause errors in a circuit due to noise. The relationship between temperature and...

We can make a wirewound resistor by winding resistive wire into a coil around an insulating core. We can also make an inductor by using a more conductive wire and winding it around a ferrite core. Both are essentially a coil of wire around a core, so what makes...

Precision and Power Resistors Resistors are often designated as precision or power. Precision resistors are designed for applications where tight resistance tolerance and stability are primary considerations, and they generally have restricted operating temperature...
