SQF7

Fusible Resistor Type SQF Series Key Features I I I I I I Overheat fusing Various current ratings Up to 2.4 Watts continuous power 2 sizes Values up to 50K Suited to overloading and to overheating As the Thermal fuses are incorporated, these cement filled resistors respond quickly to overloading as well as to external overheating. The SQF series also provides outstanding features against surges, and are therefore suitable for the preventing of inrush current for switching regulators. Obvious economic advantages can be achieved by not having to specify a separate thermal fuse.
