Glass glaze resistors are typically made from a combination of resistive materials, such as carbon or metal oxides, which are coated with a glass layer. The glass serves as an insulator and protects the resistive element from environmental factors, such as moisture and mechanical stress.

2. Manufacturing Process

The manufacturing process of glass glaze resistors involves several steps, including the preparation of the resistive material, application of the glass coating, and curing. The resistive element is first formed into the desired shape, followed by the application of a glass glaze. The resistor is then heated to cure the glass, ensuring a strong bond between the coating and the resistive material.

B. Functionality and Applications

1. Electrical Characteristics

Glass glaze resistors exhibit excellent electrical characteristics, including low temperature coefficients and high stability. These properties make them suitable for precision applications where consistent performance is critical.
