RIBWOUND RESISTORS - FIXED AND ADJUSTABLE 40 WATTS TO 2000 WATTS

Ribwound resistors have been a main product line at Milwaukee Resistor Corporation for years. Ribwound resistors are particularly useful where high energy is to be dissipated in the lower ohmic ranges. Precision winding machines, designed and manufactured by MRC, allow uniform windings to be applied extremely close to each other resulting in significantly higher resistance values (three or more times higher than normally available). Replacements for many standard round-wire resistors are available resulting in significant savings in space and cost.

Benefits/Features

Features of the Milwaukee Resistor Corporation Ribwound resistor include:

Terminal bands are spotwelded after installation on the core and then a resistance-alloy ribbon wire is crimped and edgewound onto the core.

Resistance wire is spotwelded to the terminal bands and then "locked" onto the core with a vitreous enamel, cement, or silicone coating.

Design allows for efficient heat dissipation at higher temperature ranges so the resistor is half the physical size of an equivalent rated roundwire resistor.

Fixed, adjustable, or tapped styles with single or double quick connect terminals, special temperature coefficients, and special tolerances are available.

Mounting available with spring clips (through 1-1/8" diameter); through-bolt mounting hardware, horizontal "L" mounting brackets, and individual or multiple stacked bracket assemblies.

Hardware can be supplied mounted, as loose assemblies, or as individual parts.

300 watt stock ribs available for immediate delivery.

Ratings are based on a temperature rise of 375°C. above an ambient of 40°C.

Standard resistance tolerance is ±10%. Closer tolerances available upon request.

Applications

Typical applications where enclosed resistor packages are utilized include:
