Riedon launches new high-performance metal-clad braking resistors
Riedon is proud to announce our new line of metal-clad braking resistors, the BR series. These rugged braking resistors are less reliant on heatsink configuration than resistors using other technologies like thick film or foil. Utilizing aluminium housings, high...
Cross Reference for TO Package Power Resistors
What is a TO Package? The increase of power capabilities for transistor technology lead to the development of device packages capable of dissipating much greater amounts of heat. These specialized packages are referred to as transistor outline, or TO package. The...

Inverter Power Resistor Applications The image below shows a typical inverter topology with the various resistor requirements highlighted. These requirements may include filter resistors, snubbers, gate resistors, bleeders, balancing resistors, voltage dividers,...
Discover the new RSW series of compact shunts
Riedon is proud to introduce our newest ammeter shunt offering, the RSW series. This compact and versatile series is ideal for applications such as junction boxes used in the cathodic protection industry or high current power conversion monitoring. RSW - compact size...
Bourns Model PWR4412 Series
Bourns® Model PWR4412 Series Obsolescence Bourns has announced the obsolescence of their PWR4412 series of metal element current sensing resistors. Customers should not worry because Riedon has an exact drop-in replacement, our MSR series. Here is the data...
Shunt FAQ – term origins and definitions
DC Ammeter shunt – The term DC ammeter shunt stems from one of the early uses of the devices as a means of measuring DC currents in a circuit utilizing a simple analog milli-volt meter. Many of the terms associated with these products are directly related to this...
High Current Fuse Holders
What are fuses? High current fuse holders are designed to work in conjunctions with appropriately rated fuses. Fuses are safety devices used to limit the amount of current through an individual circuit branch, or to limit the amount of current delivered from a...
Riedon’s PF2272 and PF2273 now with resistance values up to 1Mohm
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 1MΩ. By...
Temperature Coefficient of Resistance in Foil Resistors
Temperature Coefficient of Resistance refers to how the resistance value varies due to changes in temperature. One of a foil resistor’s most important properties is Low Temperature Coefficient of Resistance, or TCR. This is especially true for applications like...
Pulse Applications and Wirewound Resistors
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...
