NFR25/25H
Fusible, Non-Flammable Resistors
Vishay BCcomponents
The power that the resistor can dissipate depends on the operating
temperature.
The resistors will fuse without the risk of fire and within an indicated
range of overload. Fusing means that the resistive value of the resistor
increases at least 100 times.
The fusing characteristic is measured under constant voltage.
