Remarks: RX20 50W 10Ω ±5%, Model: RX20-50-10RJ; Low inductance, add the letter N to the model number, for example: N RX20-50-10RJ
For optimal performance and longevity, it is recommended to use resistors with a 1.5 times power margin in circuits. For example, with circuit voltage 100V and current 0.01A, calculated power: P = 100 * 0.01 = 1W. Instead of using a 1W resistor, calculate 1 * 1.5 = 1.5W, requiring a 2W resistor for safe operation.
