Fast Acting, Molded Styles,

Custom Designed For Your Application

FEATURES

• Low temperature coefficient (down to 30 ppm/°C)

• High

temperature

silicone

molded

package

(derated to 200 °C)

• Performs function of resistor and series fuse and provides

predictable fusing times

• Complete welded construction

• No flaming or distortion of unit under sufficient fusing

conditions (contact factory for details)

• Ideal for squib circuit applications and protection of

semi-conductor devices

• Negligible noise and voltage coefficient

• Material categorization: for definitions of compliance

Notes

values equal to or higher than the crossover value.

• Be aware that the inherent compromise involved between resistive and fusing functions sometimes makes certain exact combinations

unattainable. However, in nearly all cases, this does not prevent the production of a functional, reliable fuse resistor thoroughly capable of

meeting application requirements.
