Non Inductive Fixed Wirewound Resistor High Power Ceramic Tube


Non Inductive High Power Ceramic Tube Fixed Wirewound Resistors


Structure

1.The high temperature resistance ceramic tube is used as the resistance matrix,is wound with chrominum alloy wire ,then coated with high temperature & nonflammable resin for protection to let resistors with better appearance and heat dissipation effect, after natural drying,baking at different temperatures before assembly.

2.Different assembly & fitting available;

3.Single unit with multi-resistance/ Multiterminals also available;

4.Non-inductive & variable type on requests;

5.Ideal electronic component to be assembled inside high-power load bank for testing for flexible installation mode.


Features

1.In different applications,called ceramic wirewound resistors,ceramic tuberesistors,high power resistors,ripple resistors,braking resistors,charge resistor,discharge resistors,dump load resistors,current limiting resistors,aging resistors or load resistors,ect.

2.High power,shock resistance,fast heat dissipation,high stability,long life & fast delivery .

3.Taps/Termianls leading out for bolts/wire connection ;
