Ohmite Manufacturing Co. Chassis Mount Resistors TAP2000K5R0E

The Ohmite TAP2000 series resistor, specifically the part number 99AC8571, is a high-power thick film resistor designed for applications requiring significant power dissipation. It has a power rating of 2,000 watts when properly heatsinked, with a maximum working voltage of 5,000 V DC and a maximum continuous current of 120 A. The resistance value is 5 ohms with a tolerance of ¬±10%. This resistor features a non-inductive design, making it suitable for variable speed drives, power supplies, and motor control applications. It operates effectively within a temperature range of -55¬8C to +155¬8C and has a temperature coefficient of ¬±150 ppm/¬8C. The TAP2000 series is also RoHS compliant and demonstrates high insulation resistance, with values exceeding 10 GOc at 1,000 V. Engineers should consider this resistor for high-wattage applications where thermal management is critical, as it requires proper heatsinking to maintain performance. The design includes a resin-filled epoxy casing for enhanced insulation and durability.
