Resistors Technologies Distributor

Resistors Resistors are one of the commonly found passive components in an electrical circuit, together with presence of capacitors and inductors. They are primarily used to create and maintain a safe current within the circuitry itself. IBS Electronics has been the leading distributor of resistive products for high current, high voltage, and high energy applications for over 30 years.

Resistors are elements of electrical circuits that resist and reduce the flow of current through the electrical circuit. They can also be used to provide specific voltages to active components. Resistors are available with fixed or variable resistance values. Fixed resistors are ones in which resistance never changes. Variable resistors, sometimes called potentiometers, allow resistance to be adjusted. Resistor values are measured in Ohms and a resistor's composition and construction determines the amount of resistance offered. Typically resistors are constructed of metal or carbon and are available in a variety of mounting styles, but through hole and surface mount are the most common.

Resistors are available at IBS Electronics from industry leading manufacturers. IBS Electronics is an authorized distributor for many resistor manufacturers. IBS has offered a full line of Surface Mount Components by selling directly to OEM customers. Supply Chain Management solutions support are also provided.

IBS Electronics offers one of the widest ranges of resistors available to electronics designers and manufacturers including aluminium housed high power range, bare element resistors, precision power wirewound SMD resistor family, axial thin film, silicon coated types and precision passivated chip resistors and resistor packs. Typical applications include traction, snubbers, switched mode power supplies and non-inductive resistors for high frequency and pulse applications,

SMD resistor sizes

The size of SMD resistors is indicated by a numerical code, such as 0603. This code contains the width and height of the package. So in the example of 0603 Imperial code, this indicates a length of 0.060 and a width of 0.030.
