Vishay Axial Cemented Wirewound Safety Resistors are designed for operation as fusible safety components. These resistors are specially formulated lacquer coating that offers enhanced thermal and electrical insulating properties. The axial cemented wirewound safety resistors operate within a tempeature range from -40°C to +200°C and ,aximum power rating of 5W. These components offer tolerance of ±5% and resistance range from 3Ω to 100Ω. Typical applications include energy meters, LED drivers, power supplies, and white goods.
