Everohms Fusible Chip Resistor - FCR Series
The Everohms FCR Series Fusible Chip Resistors are designed for safety circuits in a wide range of electronic applications. These resistors offer accurate fusibility, are small and lightweight, and feature a low temperature coefficient (under 600 PPM/) and a noncombustible insulated coat. They can also be used as general-purpose resistors.
