■ Product features
The RXBW-T adjustable ripple wire wound resistor uses high-temperature resistant material as the resistor substrate, with high insulation and non combustible filling material filling, tightly integrated with the resistor substrate, resistance wire, and metal shell, and has high stability and thermal conductivity. Based on extensive market research and engineering tests, a carefully designed aluminum alloy housing with heat dissipation fins has greatly improved the heat dissipation performance of this resistor compared to traditional resistors of the same volume and power. It not only significantly reduces the surface temperature rise of the resistor body, but also greatly improves its load resistance and long-term stability. Its service life can reach 1.5 to 2 times that of traditional resistors.
1. Good heat dissipation performance, impact resistance, high stability, and long lifespan.
2. Small size and high power load.
3. Widely used in various mechanical industries such as frequency converters, elevators, ships, motors and high-end equipment, load aging testing, etc.
4. Accuracy range: ± 5%, ± 10%

■ Suggestions for using resistors
It is best to leave 1.5 times the power margin for resistors in circuits. For example, if the voltage in the circuit is 100V and the current is 0.01A, the calculated power is P=100 * 0.01=1W. At this time, a resistor of 1W cannot be used, and 1 * 1.5=1.5W is calculated. If there is no 1.5W resistor, a resistor of 2W is needed.
