The SL-4 series from Riedon utilise wirewound technology to offer great precision, high temperature ratings of up to 275°C, low temperature coefficient and superior surge handling capabilities, all within a surface-mountable package. With resistance values between 0.0058Ω and 0.07Ω and power ratings of 2W (at +70°C). The SL-4 wirewound resistors offer tolerances of ±1% to ±5%, TCR ±200 ppm/°C (for lower values contact us) and flame resistant UL 94V-0.
