Abstract
An electrical heater, an exhaust treatment assembly, and method of manufacture. The heater includes a resistive portion configured to generate heat when electrical current is passed therethrough. A plurality of slots extend into the resistive portion from an outer periphery of the resistive portion and define a serpentine current-carrying path extending through the resistive portion between a pair of electrode attachment portions. Each of the electrode attachment portions is connected to a respective end segment that is bounded between an outer periphery of the resistive portion and a respective first slot of the plurality of slots. At least one auxiliary slot in each of the end segments that extends from the outer periphery toward the first slot in a direction transverse to the first slot to bias current flow through a concentrated region adjacent to and extending along the first slot in each end segment.
