HPZ10 [2012] HPZ18 [3216] HPZ33 [3225] HPZ Anti-surge precision thick film chip resistors HPZ Series Features Structure,Materials *RPC *0.5% 50ppm/ *RPZ Part name *By making the best use of our superior thick film printing technology and laser trimming technology. The chip resistor model RPZ series is one of the highest performance resistors. Superior to RPC series in surge dielectric withstanding voltage,keeping high reliability of thick film resistors. *Resistance value permission difference equivalent to a thin coating type 0.5% and resistance value temperature characteristic 50ppm/ was materialized. *The resistance serge characteristic is equal with RPZ series. Materials Substrate High purity alumina Resistive film Ruthenium oxide based thick film Overcoat film Resin film Inside termination Ag based thick film Intermediate termination Plated Ni film Outside termination Plated Sn film Part No. Explanation (ex.)
