RI82 flat (chip-style) high-voltage resistors
Cuerpo cerámico plano, 0,25 W a 100 W, hasta 60 kV
0.25–100 W · hasta 4–60 kV
Tipo plano RI82 — elemento resistivo en zigzag sobre sustrato de alúmina
Resistencias de alta tensión planas sobre sustrato de alúmina 96 % con elemento resistivo vitrificado en zigzag. El perfil plano reduce la altura de placa y la gran superficie disipa calor con eficacia, cubriendo 0,25 W a 100 W en un volumen mucho menor que una resistencia redonda equivalente. Longitudes de 10 mm a 182 mm, aguante hasta 60 kV, paso de patillas especificado por tipo.
Materiales
| 96% Al<sub>2</sub>O<sub>3</sub> alumina ceramic | |
| Glass-glaze resistance film | |
| Tinned copper | |
| Resin | |
| Air (see notes — rating improves substantially when oil-immersed or resin-potted) |
Encapsulado: resina.
Notas sobre valores nominales
- Si se dan tensión nominal y tensión de trabajo máxima, use la menor.
- La potencia de pico de impulso debe quedar por debajo de 100× la nominal.
