Product Description

Metal glaze resistor

Sample Product

Metalglazeresistor

 

Construction

 

Metalglazeresistor

Features

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%
