Hi-tech resistors presents strip resistors. These strip resistors [2 resistors of this series] can be connected in parallel instead of four 4w wire-wound resistors. Hence in this manner, unnecessary use of 4w wire-wound resistor can be eleiminated.
Being completely non-inductive, the heal series resistors can sense current with a higher accuracy than wire-wound resistor where inductance also plays a part. The temperature rise in the circuit with these resistors is the same as with four numbers due to the difference in the resistive element and the method of construction. Resistors in circuits will result in cost as well as assembly time saving.
