Ohmite TEH140MR030FE High Power Power Resistor
The TEH140 Power Resistors are high-performance, 140-watt TO-247 molded devices designed for high frequency and pulse loading applications. These resistors feature a non-inductive design, wide resistance range from 0.010 to 510kΩ, and excellent thermal management with only 0.9°C/W heat resistance between resistor and flange. Suitable for power electronics, inverters, and industrial motor control, they offer superior durability, withstanding voltages up to 2500VAC and operational temperatures up to +175°C. Their construction includes a cermet or NiCr resistor element on alumina substrate with Ni-plated copper flange, facilitating efficient heat dissipation and reliable performance in demanding environments.
