    We also can make uncommon product per customers requirements.


    Feature:

    * Resistance range:0.01~33k ohm
    * Power range: 1/4W ~ 10W
    * Resistance tolerance: +/- 1% ~ +/- 10%
    * Good heat-durability, low temperature coefficient, low noise, high overload power.
    * Operating ambient temperature: -55C to +275C.
    * Surface is nonflammable, the 1/4W-6W coating is gray white and indicate the resistance value by color ring, the 7W or over will indicate the resistance value by lettering or coating is green.


    1, Good heat-durability. low temperature coefficient, low noise, high load power; nonflammability.
    2, Can be Fusible during the stated time for protecting the circuit once wording at the required overload voltage.
