Description
- The RX24 250W Wirewound Resistor is a high-power component built for consistent performance in harsh environments. It features an anodized gold aluminum housing that provides excellent corrosion resistance, wear resistance, and long service life. The concave-convex surface groove design enhances heat dissipation and mechanical strength, ensuring stable operation under continuous load.Inside, the resistor adopts a ceramic core wound with premium alloy wire, delivering accurate resistance values, low inductance, and strong thermal conductivity. The resistive core and aluminum case are firmly bonded with high-insulation, non-flammable potting material, forming a compact and vibration-resistant body that is shielded from dust, humidity, and external mechanical stress.
- The terminals are made of tinned copper or optional screw/perforated connections, offering flexibility for different installation needs. This model also supports customized lead styles, including welded high-temperature wire, to meet specific application requirements.
- Constructed from industrial-grade 6063 aluminum, the RX24 250W offers a low temperature coefficient, high precision, and superior heat management, making it well-suited for current sensing, low inductance circuits, precision power applications, and high-reliability equipment. Its robust design ensures long-term stability in power supplies, inverters, motor drives, and other demanding systems.
