    Hi,
    i want to use power resistor to heat up a surface from (30~70 degre celsius).
    the area is quite small 3x3 cm and so i want to use single small power resistor
    and a control circuit.
    Can someone recommend me a power resistor for this purpose?
    i want to use it with a supply around 12 v from dc supply.

    If you use the bolt-on type resistor be sure you use a thin layer of thermal grease to mount it on the plate.
