Glass glazed rod-shaped resistor paste

Glass glaze rod-shaped resistor paste is a paste made by mixing metal oxides (such as palladium oxide, ruthenium oxide, etc.) of precious metals (such as silver, palladium, ruthenium, rhodium, etc.) with glass glaze adhesive. This slurry is processed through specific techniques and coated onto an insulating skeleton (which may be a rod-shaped structure made of ceramic or other insulating materials), and then sintered at high temperatures to form resistors with stable resistance values.

Product Features

Wide resistance range: Glass glaze resistors typically have a wide resistance range, ranging from 5.1 ohms to 200 megaohms (Ω), to meet the needs of different circuits.

Small temperature coefficient: The temperature coefficient of this resistor is small, which means that its resistance value does not change significantly with temperature and can maintain a stable resistance value over a wide temperature range.

Good moisture resistance: Glass glaze resistors have good moisture resistance and can maintain stable performance in humid environments.

Good high-frequency characteristics: suitable for high-frequency circuits, with low noise and good high-frequency response characteristics.

Small size and light weight: The rod-shaped design allows resistors to maintain high performance while having a smaller volume and weight, making them easy to integrate into electronic devices.

Production process

1. Raw material preparation: Select suitable precious metal oxides, glass glaze adhesives, and other auxiliary materials.

2. Mixing and stirring: Mix the raw materials in a certain proportion, and add an appropriate amount of solvent and additives for stirring to form a uniform slurry.

3. Coating: Apply the slurry onto the insulation skeleton to form a certain thickness of resistance layer.

4. Sintering: The coated insulation skeleton is sintered at high temperature to solidify the slurry into a stable resistance layer.

5. Testing and Inspection: Test and inspect the sintered resistors to ensure that their resistance values, temperature coefficients, and other performance indicators meet the requirements.
