Riedon, Inc. has published these technical articles:

(Passive and Discrete)
From this Article:
In our data sheets the nominal power dissipation is mentioned for all resistors. The data are mentioned for a free standing assembly i.e. SMD assembled on a PCB. The ambient temperature is always...
(Passive and Discrete)
From this Article:
Current sensing is used in many applications. From microamperes to thousands of amperes, sensing is usually accomplished through two effects: voltage drop or the generation of magnetic fields. This...
(Passive and Discrete)
From this Article:
Modern industrial automation applications demand high performance instrumentation. A well-established technique is to use 4-to-20 mA current-mode transmission (rather than voltage signal) between...

From this Article:
In today's modern fields of measurement and electronics, particularly in such industries as heating and ventilation (HVAC), medical technology, and military applications: precision, stability, and...
(Passive and Discrete)
From this Article:
Perhaps your early electronics experience was with communications equipment when vacuum tubes were king. Tubes had personality. They emitted a warm glow from their filaments and cherry-red anodes, and...

From this Article:
The absolute ohmic value of a resistor is temperature-dependent.In today's modern fields of measurement and electronics, particularly in such industries as heating and ventilation(HVAC), medical...
(Passive and Discrete)
From this Article:
A resistor's Temperature Coefficient of Resistance (TCR) tells how much its value changes as its temperature changes. It is usually expressed in ppm/°C (parts per million per degree Centigrade) units....
(Passive and Discrete)
From this Article:
Power resistors and resistance heaters share many common design considerations. In both products, good thermal design ensures low thermal resistance between the element and the exterior environment....

From this Article:
Riedon has manufactured high-precision wirewound resistors for OEM industries since 1960. These precision resistors have tolerances as small as 0.005%. They are extremely stable over time, and operate...
(Passive and Discrete)
From this Article:
Wirewound resistors have been around for a long time. They enjoy a long life because they have some very important features not duplicated by new technology products. If you must optimize circuit...
