The SBCHE447RJ is a power wirewound resistor from the SBC series, housed in a square ceramic case for high-power applications. This component provides a resistance of 47 Ohms with a ±5% tolerance and has a power rating of 4 watts, corresponding to the SBCH-4 model. Its construction features a resistive element sealed within a fluted ceramic case with an inorganic silica filler, ensuring high insulation resistance and the ability to withstand high overload currents. The 'E' designation indicates one lengthened lead to facilitate vertical mounting. These resistors are ideal for use in power supplies, fan force ovens, cooker hoods, and triac-based speed controls where performance and reliability are critical.
