Electrical Heaters For Exhaust Aftertreatment Systems and Assemblies

An electrical heater assembly comprising:

• a heater body defined with respect to an axial direction and a radial direction, the heater body comprising:
• a diameter or cross-sectional dimension extending in the radial direction;
• a resistive portion;
• a plurality of slits in the resistive portion that electrically disconnects sections of the resistive portion from each other to define a serpentine current-carrying path through the resistive portion;
• an electrode attachment portion connected at an end of the serpentine current-carrying path, and
• an electrode comprising a first end that is electrically connected to the heater body at the electrode attachment portion, wherein the first end extends in a transverse direction from the heater body that is transverse to the diameter or cross-sectional dimension.
