Description

LOW OHM POWER RESISTORS

The special construction characteristics of the metalband resistors of Fukushima Futaba offer in comparison to the already known axial lopped wirewound resistors many advantages. The resistor element is punched like meander out of a special metalband (special alloy of Ni/Cr/Fe/Cu). On this element the lead wires are welded without caps.

This two-dimensional type therefore only has a very low inductive resistance. The negative effect of the enormous temperature decrease of the 'hotspot-zone' in the mid of the resistor to the both ends which is well known from axial and lopped resistor will not occur when using MPC resistors as the lead wires have a much smaller surface as the element and they are not lopped. This construction results in an steady thermal distribution over the element. The metalband element is housed in and hermetically closed ceramic case supporting the optimal thermal characteristics. Idle zones in the case are filed before shutting with special cement with ceramic powder.

Because of the steady heat dissipation over the complete case, there is the possibility to increase the rating capacity many times, when slipping over a suitable cooping cap over the resistor case.
