Characteristic Resistance

A lead resistance of 30 milliohms has a negligible effect on a full module but has a catastrophic effect on a single cell coupon. Series Resistance and Power Loss. As long as the power loss is reasonable (< 20%), the characteristic resistance also allows for a conversion between the fractional power loss and series resistance in Ω or Ω cm².

Thermal resistance, thermal spreading and temperature

varies from module to module even if the internal module setup is the same. The differences are attributable to the methods of measuring ΔT and the type of the heat sink. In Vincotech''s test setups, modules are mounted on water-cooled, copper heat sinks so very little heat spreads within the semiconductors, the DCB and the baseplate
