Chassis Mount Power Resistors Handle Shock And High Heat

Ruggedly constructed to endure shock, vibration and high temperatures, the AL chassis-mount power resistors offer power ratings from 5W to 50W at 25°C and can withstand up to 275°C of heat. They are available in values from 0.01 ohms to 180 kilohms with tolerances down to ±1% and sport a welded and molded construction. In addition, TCRs as low as ±20 ppm/°C (less than or equal to 10 ohms) are said to be exhibited. Versions of the components qualified to MIL-R18546 are also available. Prices range from $2 to $30 each based on production volumes. INTERNATIONAL RESISTIVE COMPANY, INC., Boone, NC. (828) 264-8861.
