The TE500B220RJ is a high-power wire wound resistor from the TE Series, designed for heavy-duty industrial applications requiring stability and reliability. It features a mullite-coated tubular ceramic core with a corrugated ribbon element that enables rapid cooling and supports power ratings from 50W to 2500W. The resistor operates over a temperature range of -25°C to +225°C with a temperature coefficient of resistance within ±440ppm/°C, and demonstrates exceptional durability through 3x overload capability for 5 seconds and flameproof construction. Key electrical characteristics include insulation resistance exceeding 100MO at 500V DC, voltage withstand capability of 2500V AC for 1 minute, and tolerance of ±5% for resistance values from 1O to 2.7kO. This resistor is ideal for large electrical and production machinery, motor control, dynamic braking, load test simulation, and equipment discharge applications where robust performance and thermal management are essential.
