TPAN1331 Planar Non-Inductive Power Resistor

The TPAN1331 series is a high-power molded power resistor, also known as a TO-331 package high-power resistor. It features a planar non-inductive design and is suitable for applications requiring current detection, energy absorption and dissipation, RC absorption, high-speed switching, and high-frequency circuits. It is also used in voltage regulation, constant power loads, and low-energy pulse loads. Key advantages include excellent long-term stability, low temperature coefficient, high heat dissipation, low thermal resistance, and low current noise. The product is manufactured with independently controlled core materials, equipment, and processes, ensuring stable quality and timely delivery.
