“Common Applications and Functions of Resistors in a Circuit” Whitepaper

For resistive products to meet the needs of different applications, they need to be available in different construction types. Ohmite’s power resistors cover some of the market’s most popular constructions; we’ve highlighted wirewound, wirewound heat-sinkable and composition products in this edition. Learn more about resistor fundamentals and applications in our featured whitepaper resource.

Wirewound Resistors

Wirewound Axial Resistors

20 Series Axial

The durable and economical series of axial terminal resistors offers an extensive range of 1 W up to 10 W in 6 different sizes.They’re ideal for computer, communications, and industrial applications.

Wirewound Resistor for Harsh Environments

270 Series

The 270 Type series of resistors are a great option for applications that require wattage ratings from 12 to 1000 W. Thanks to all-welded construction and durable lead-free vitreous enamel coating, 270 Series is also ideal for harsh environments.

“Common Applications and Functions of Resistors in a Circuit” 

Resistors carry out a number of functions in electronic circuits, such as reducing current flow, adjusting signal levels, and dividing voltages. Review the fundamentals of resistors and their many uses in this free whitepaper.

Wire-Wound Heat-Sinkable

ARG Aluminum Housed Resistors

ARG Series

Aluminum-housed ARG Series resistors were built to withstand industrial applications subject to vibration, shock, and harsh environmental conditions. The series is available in power ratings from 150 W to 400 W with proper heatsinking.

Aluminum Housed Resistors

HS Series

An extension of the popular Arcol HS Series, this aluminum-housed resistor series is wound to maximize high pulse capacity. It offers ohm values of 3.6-1200 and can carry a max voltage of up to 2800. It is designed for mounting to a heat sink for maximum wattage.


Fixed ceramic resistors

OX/OY Series Axial

The OX/OY Series of fixed ceramic resistors provides enhanced performance in high voltage power supplies, R-C snubber circuits, and inrush limiters. These resistors can often replace difficult-to-source carbon composition resistors.

Tubular High Energy Bulk Ceramic Resistors

800 & 1000 Series Tubular

For excellent performance in high peak power or high-energy pulses, Ohmite offers the 800 & 1000 Series of tubular high-energy bulk ceramic resistors. These rugged resistors are non-inductive, have no film or wire to fail, and come in three distinctly different ceramic materials to meet a range of demanding requirements.
