    White Rectangular Heated Cement Resistor in Series Ceramic Composition 16 Watt  3.3ohm E24 Resistance with High Temperature Cable

    Product Description:

    Cement resistors are made by winding the resistance wires on the alkaliless ceramic cores,then coated with noncorrosive, heat-proof and humidity-proof material. Cement type is the one with special flameproof cement stuffed in the ceramic case.


    1. Small dimension,excellent stability in high temperature,resistant to humidity and shock.

    2. Completely insulated character suitable for household appliance.

    3. Precision resistance values with longer life.

    4. In high resistance values,the winding cores will be replaced by power film cores.

    5. Super heat dissipation;small linear temperature coefficient.

    6. Instant overload capability; low noise figures and low annual shift on resistance values.

    - Temperature coefficient: +/-300ppm/celcius

    - Insulation resistance: >100M ohms

    - Load life (1000 hours): +/-2%, +0.05 ohm

    - Short-time overload: +/-2%, +0.05 ohm

    - Dielectric withstanding vollage: +/-1%, +0.05 ohm

    - Moisture resistance: +/-3%, +0.05 ohm

    - Shock and vibration: +/-1%, +0.05 ohm

    - Soldering heat: +/-1%, +0.05 ohm

    - Incombustibility: EX 16 times V, 5 minutes

    Temperature coefficient

    Test the resistance value at normal temperature added 100,calculate per ℃ resistance value rate.


    Short time overload

    1~4W:According 5 times rated voltage ,5~10W: According 10 times rated power to account the voltage or max .overload voltage (get the lower)for 5 seconds.



    Resistance to soldering heat

    Immerge into the 350±10℃ tin stove for 2~3 seconds.



    Immerge into the 245±3℃ tin stove for 2~3 seconds.

    The area of soldering is over 95%

    Temperature cycling

    At -55℃ for 30 min,then at +25℃ for 10~15 min,then at +275℃ for 30 min,then at +25℃ for 10~15min, total 5 cycles.


    Load life in humidity

    Overload rated voltage or Max. working voltage(get the lower)     for 1000 hours (1.5 hours on and half-hours off) at the 40±2℃ and 90~95% relative humidity.


    Load life in heat

    Overload rated voltage or Max. working voltage(get the lower)m for 1000 hours (1.5 hours on and half-hours off) at the 70±2.
