CRF257-45T10R 4,3Watt Fusible WW Resistor,10R

In the series, the CRF parameters are designed substantially to applications where the fault is clearly defined, especially power supplies and chargers for mobile use.

Resistances of the series CRF release abruptly in presence of a mains voltage 230Veff out without the occurrence of fire or explosion.

Beyond this, the resistors can be used in case of overload application as a backup resistors.

The resistance wire is wound on a ceramic substrate capped and welded to the caps. A special paint takes on the case of evaporation of the wire to the metal vapor and prevents arcing and thus short-circuiting.

The winding wire is for all resistance values ??between 10R and 330R sized so that the evaporation occurs at line voltage.

The resistance elements are coated with silicone varnish.
