RI80B Series High Voltage Film Linear Glass Glaze Resistors |
Product Overview
The RI80B Series High Voltage Film Linear Glass Glaze Resistors are designed for high-voltage DC circuits and precision high-voltage measurement systems. Manufactured using a high-quality ceramic substrate with a glass glaze resistive film, these resistors offer excellent voltage withstand capability, outstanding stability, and long-term reliability.
The resistance value is accurately adjusted by a precision helical trimming process, providing excellent linearity and consistent electrical performance. The RI80B series shares similar electrical characteristics with the RI80 series while featuring a different mechanical structure. Various resistance values, dimensions, voltage ratings, and power ratings are available to meet customer-specific requirements.
