Striking a Balance!

Riedon’s Balancing Resistors Balancing resistors provide a way for sharing a load between two or more DC-DC converters or power transistors. Using two smaller devices in parallel may have cost, thermal, or physical advantages when compared to one device of...

Relax. No need to inrush.

Inrush limiting resistors Inrush limiting resistors of a few Ohms or less in series with the AC line can address a problem with AC-DC converters where a large surge current may occur as the device powers up and the bulk storage capacitors initially charge.  One...

Let there be light!

Powering LED’s With Resistors Efficient and reliable operation of LED lighting is dependent on the right choice of current-limiting resistor. in many situations the necessary ballast resistor is likely to dissipate several Watts of power. This not only dictates...

Let us take your pulse

Pulse Withstanding Resistors Determining the right pulse handling capabilities for a particular application is not always easy. Dealing with inrush current is different than dealing with transient suppression, for example. For pulses of up to five seconds, the...

Typical resistors parameters and their meanings:

Resistor Paramaters • Impulse strength is the maximum allowed short-duration (impulse) electric energy that the resistor can withstand without exceeding the limiting temperature. • Limiting voltage, also referred to as dielectric strength, is the maximum allowable...
Precision or Power?

Precision or Power?

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...

Bleeder Resistor

Bleeder Resistor Bleeder Resistors are used as a safety feature to discharge capacitors to safe voltage levels after power is removed. A bleed resistor may be either connected permanently for cost effectiveness and high reliability or switched across a capacitor for...
