Bourns® Models CMP/CMP-A are anti-surge devices that feature a wide resistance range from 1 ohm to 1 megohm and high rated power up to 1.5 watts. Supporting even higher power designs, the Bourns® Model CHP-A resistor series delivers triple-rated power, with one model that provides 3 watts of rated power at 70°C, which is one of the highest rated resistor power offerings in the industry.

Resistors have traditionally been manufactured by a variety of methods and technologies, including metal and metal-oxide film, metal foil, carbon, wirewound, and thick-film methods. Each has specific characteristics that make them more or less suitable for high-temperature applications. Resistor degradation at a high temperature can vary from a small resistance change over time to a catastrophic change in resistance, exhibited by either becoming open circuit or, in some cases, a short circuit.

Resistor Markets Tighten as Ruthenium Prices Skyrocket

  • 0
Unprecedented increases in the price of ruthenium, a key element in the production of thick film pastes used in thick film chip resistors, has resulted in extended lead times for the ubiquitous resistor component. Because of the large percentage of variable costs in the production of chip resistors relying on raw materials, expect price increases and short supply for the rest of CY 2021 and FY 2022.

An Overview of Electrical and Electronic Fuse Markets and Technologies

A fuse is an electrical or electronic circuit protection device that protects a circuit against overcurrent, either by melting or fusing open its conductive element when excessive current flows through it. Some fuses are single-use or “one-shot” designs; others are reusable designs. This is an important distinction in the marketplace among design engineers.

Non-Wirewound Resistors: Film, Foil & Metal Oxide

  • Posted by Tomáš Zedníček

Introduction to Film Resistors Film resistors are built either on cylindrical rods or on planar substrates. Usually, the material in the rods and substrates is ceramic in the state of aluminum oxide (alumina), but glass may occur. Hollow cores exist but are more and more abandoned when sizes are becoming smaller. This design suffers also from drawbacks: the construction is more fragile and the heat dissipation is poorer than that of a solid core.
