The nominal resistance is 47,000 ohms, commonly denoted as 47K. The unit “K” represents kiloohms, indicating a thousand ohms. The resistor can handle a maximum power dissipation of 0.25 watts without being damaged.The tolerance of 5% means that the actual resistance of the resistor can vary by up to 5% from the specified 47K ohms. The tolerance provides a range within which the actual resistance may fall.
