Cylindrical Glass Glaze High-Voltage Resistor
Factory Direct · RI80 Cylindrical Glass Glaze High-Voltage Resistor
Glass glaze · Metal film · Non-inductive — Custom non-standard · Invoice supported · 2-year warranty

three-in-one process: glass glaze + metal film + non-inductive
Uses a three-in-one process: glass glaze, metal film and non-inductive winding. Glass-glaze sintering ensures high withstand voltage and long-term stability; metal-film construction improves accuracy; non-inductive designeffectivelyreduces parasitic inductanceamount, suitable forhigh-frequencyhigh-voltagePulseChargeScenarios.

Nickel-plated H62 brasscap + oxidation-resistant tin-plated copper lead wire
Caps use nickel-plated H62 brass with good conductivity and corrosion resistance; leads use oxidation-resistant tin-plated copper wire with high flexibility / solderingreliable; termination constructionmature / long service life.

1W ~ 1000W full power coverage · 5KV ~ 120KV full withstand-voltage range
The RI80 series covers 1W ~ 1000W and 5KV ~ 120KV with two termination options: a (Lead Wire) or b (Stud) in M4 / M5 / M6 / M8 / M10. Custom non-standard / invoice supported, 2-year warranty.
