Providing design engineers with a higher wattage device without increasing the package size, TT electronics IRC has increased the power ratings of its PWC Series resistors. IRC now offers the pulse-withstanding chip resistors in 1/2W (1206 size, increased from 1/3W); 1W (2010 size, increased from 3/4W); and 2W (2512 size, increased from 1.5W)..
