<p>The filter heater (1) has a circuit board (2) on which electronic component (3) is arranged. The mechanically resilient springs are arranged against the electronic component and arranged against a ground pole (5). An electrically conductive fuse element (4) is connected to the electronic component and/or the ground pole through a temperature-sensitive material (7). The temperature-sensitive material releases the connection when reaching or exceeding the predefined limit temperature so that current flow is interrupted, and the filter heater is switched off.</p>
