Ohmite's Little Demons are small, reliable carbon composition resistors with exceptional strength. They are made tough by a molding process that combines the leads, insulation and resistive element into an integrated unit. Along with their small size, Little Demons perform with low noise, dissipate heat rapidly and offer high temperature stability.
Color codes are readable even after prolonged use thanks to a very durable coating that resists abrasions and chipping normally associated with automatic insertion equipment.
FEATURES
* Molded insulation for high dielectric strength.
* Rugged construction.
* Available in Resistor Cabinet Assortments & 100 pc packs.
* High surge capabilities.
* Comparable to "Mil" RC07, RC20, and RC32 types.

|
|
Powr-Rib® Series
Edgewound/Round Wire Power Resistors
Designed in both Edgewound and Round Wire formats, these rugged resistors can handle 700 to 1000 Watts of power. Specify our edgewound design for very low resistance and high power capacity. When higher resistance with lower power capacity is required use our round wire design.
Constructed of a heavy resistance alloy mounted on ceramic insulators and supported by a metal mounting bracket. Metal parts, except for the resistance element, are heavily plated to prevent oxidation at high operating temperatures and to prevent corrosion. The mounting bar is slotted on each end to facilitate installation. Edgewound units provide clamp-type terminals, permitting a reliable connection which can be moved along the resistive element to obtain intermediate values.
SPECIFICATIONS
Electrical
* Current Rating: Continuous duty as listed
* Wattage Rating: 700 to 1,000 (up to 1,600 watts on special order)
* Resistance Tolerance: ±10% standard, ±5% available
* Terminals: Clamps, movable along resistor wire for setting intermediate resistance values on Edgewound units (current must be derated in proportion).
* Temperature Coefficient: ±300 ppm/°C for resistors 50 amps and more; ±500 ppm/°C for resistors 47 amps or less
* Ohmic Values: See chart
* Mounting: Metal mounting bar is slotted on each end to facilitate installation.
Edgewound units have clamp-type terminals which permits a reliable connection and can be moved along the resistive element to obtain intermediate values.

These wirewound resistors are equipped with an adjustable lug, making them ideal for adjusting circuits, obtaining odd resistance values and setting equipment to meet various line voltages.
210 Type resistors feature a hollow core to permit secure fastening with spring-type clips or thru bolts with washers. They also offer the durability of lead free vitreous enamel coating and all-welded construction.
Mounting brackets not included with resistors (more mounting info).
FEATURES
* Terminals suitable for soldering or bolt connection.
* Adjustable lug supplied.
* High wattage applications.
* All-welded construction.
* Rugged lead free vitreous enamel coating.
* Flame resistant coating.
* Thumb-screw-adjustable lug available (Part No. 2160) for 1.125" core resistors.
SPECIFICATIONS
Material
* Coating: Lead free vitreous enamel.
* Core: Tubular ceramic.
* Terminals: Solder coated radial lug.
* Adjustable terminal: Nickel plated steel. (Screwdriver type adjustable lug supplied standard. Other types, including silver contact units, available.)
* Derating: Linearly from 100% @ +25°C to 0% @ +350°C.
Electrical
* Tolerance: ±10% (K)
* Power rating: Based on 25°C free air rating. The stated wattage rating applies only when the entire resistance is in the circuit. Setting the lug at an intermediate point reduces the wattage rating by the approximate same proportion. Example: If the lug is set at half resistance, the wattage is reduced by approximately one-half.
* Overload: 10 times rated wattage for 5 seconds.
* Temperature coefficient: ±260 ppm/°C
* Dielectric withstanding voltage: 1000 VAC: 12 to 100 watt rating. 3000 VAC: 175 and 225 watt rating (measured from terminal to mounting bracket)
* To calculate max. amps: use the formula
Power limitations for high resistance values: When resistance exceeds the resistance values listed at right, derate the Power Rating by 25% to improve reliability:
