HEI FVT16020E-1 Vitreous Enamel Power Resistor 5 Ohm 175W

The HEI FVT16020E-1 is a high-power, fixed vitreous enamel tubular resistor designed for industrial and electronic applications requiring robust energy dissipation. Manufactured by Huntington Electric Inc. (now part of Vishay), this resistor features a 5 ohm resistance with a ±5% tolerance and a 175W power rating, making it suitable for load banks, motor controls, power supplies, and dynamic braking systems. Its ceramic core and vitreous enamel coating provide excellent thermal stability, vibration resistance, and protection against moisture and contaminants, ensuring reliable performance in harsh environments. The multi-tap design with 7 tap spacings allows for flexible circuit configurations, offering advantages over single-tap resistors by enabling adjustable resistance values without additional components. Benefits include high overload capacity and long-term stability, though drawbacks may include larger size compared to wirewound alternatives and potential heat generation requiring proper mounting and ventilation. Compared to similar products like Ohmite's L series, the FVT offers superior enamel durability for high-temperature operations up to 350°C. This unit appears used based on visual wear but remains functional for demanding applications in manufacturing, automation, and power electronics.
