New high-power non-inductive resistor (TAP120) enforces mechanical stability available,Contact us with your specific needs.
Direct is devoting in the development of thick film non-inductive power resistors in particularly and powerful compact.
Non-inductive Thick Film (TAP120) Ultra-High-Power Resistors packaged in SOT227 with alumina ceramic metalized on the bottom for optimum discharge and improved heat transfer. Case encapsulates with resin-filled epoxy and enables large air distance between the terminals to achieve high insulation resistance.
Power Resistor (TAP120) handles power peaks, including those that happen whenever high-end electronic products are switched on and off, and it redirect power surges. Also Non-inductive (TAP120) help handle the rotational speed of electric motors such as those used in vehicles like locomotives and trams and in industrial equipment.
The thick flim resistor (TAP120) series consists of 4 connection options. Operating voltage can reach 1500V. Precision tolerance has 0.5%、1%、2%、5%、10% alternative. While the center temperature of the bottom plate lower than 85°C, the type 1 and type 2 can remain full power of 120W.
Direct will also produce devices outside these specifications to meet customer requirements.
