Example: RX20 50W 10Ω ±5%, Model: RX20-50-10RJ
For low inductance versions, add the letter "N" to the model number, for example: N RX20-50-10RJ
For optimal performance and longevity, we recommend using resistors with a 1.5x power margin. For example, if your circuit operates at 100V with 0.01A current (calculated power: 1W), select a 2W resistor rather than 1W to ensure reliable operation.
