Product Description
Metal Glaze Resistor
Metal glaze resistor is an electronic component that is designed to provide a fixed resistance value in a circuit. It is made by depositing a layer of metal oxide onto a ceramic substrate, which is then coated with a protective layer. Metal glaze resistors are widely used in electronic circuits due to their precision, stability, and low noise.
Structure of Metal Glaze Resistor
Features of Metal Glaze Resistor
1. High resistance value.small size. endure high temperature. high voltage good performance cnduring moisture and good overload capability
2. Operating ambient temperature:-55℃~+125℃。
3. Surface is nonflammable. The normal size coats brick red and small size coating is gray white. That add a yellow ring at the behind of the precision color rings to distinguish the resistors types.
4. Resistance tolerance: ±1%, ±2%, ±5%, ±10%

Advantages of Metal Glaze Resistors
One of the main advantages of metal glaze resistors is their high precision. They have a tight tolerance range, meaning that they provide a very precise resistance value. This is important in circuits that require accurate voltage division or current limiting.
Another advantage of metal glaze resistors is their stability over time and temperature. They are designed to have a low temperature coefficient of resistance (TCR), meaning that their resistance value does not change much as temperature changes. This makes them ideal for use in circuits that operate over a wide temperature range.
Metal glaze resistors also have low noise levels. They are designed to have a low voltage coefficient of resistance (VCR), which means that they do not generate much noise or distortion when used in audio circuits.
