Song Chuan ISO-280 Ultra Micro Flux Tight Relays - 12V DC, 20 Amp

These Song Chuan Ultra Micro ISO Automotive Relays are space saving relays with high current capacity. The best solution for full voltage applicable to head lamps, auxiliary lamps, fog horns, motors for fans, window lifters, air conditioners, heated rear windows, or the myriad of other equipment existing on vehicles today. In addition, item 74981 features a built-in resistor. While the relay permits a low current flow circuit to control a high current flow circuit, the internal resistor protects sensitive equipment against voltage spikes.
