Resistors and How they Work

Resistors start from Wires to Wirewound Types. Carbon Film Resistors are most Common, Metal Film Resistors are more stable and accurate. We have now SMD types with lower power some are Laser Trimmed Types for accurate values. Resistors Arrays are used in Digital Circuits.

Types of Resistors – Color code and Other Resources

1/4 W Resistors have a Voltage rating of around 200-250V. Even when using a High value like 1 Meg use two in series when it is across Mains 230 V AC. 470K + 470K – you get around a Meg at 500V Rating.

Resistors and How they Work

Resistor 1/4W Metal Film
A standard range of 1/4W Metal Film Resistors suitable for most applications. High stability and solid construction ensure a long and stable life. 1% tolerance for the full range from 1R to 10M.

Riedon Resistors – Wirewound, Thick & Thin Film, and also Foil resistive elements.current sense, high pulse, high surge, surface mount, power and precision wirewound resistors.

High Performance Resistor Networks from Caddock – precision resistors, high voltage resistors, current sense resistors, chip resistors, high frequency resistors, and load resistors.

Ohmite’s Audio Gold resistors have been carefully engineered with non-magnetic materials to eliminate the effects of these stray magnetic fields on circuit performance. Ohmite’s LVC Series low value chip resistors are ideal for today’s current sense applications requiring low profile, low cost solutions
