Abstract
A component having an active volume, the active volume not being centrally positioned along a height of the component, and/or not being centrally positioned along a width of the component. Use of the component is also disclosed. Further aspects relate to a use of the component and to a component. The component can be an NTC thermistor or a PTC thermistor or a temperature measurement element. Use of the component for monitoring a temperature of a battery or in a vehicle is also disclosed.
Claims18
A component, comprising:
- a first side face;
- a second side face, a width of the component extending from the first side face to the second side face of the component;
- a bottom side;
- a top side, a height of the component extending from the bottom side to the top side of the component;
- a plurality of inner electrodes, at least a pair of inner electrodes in the plurality of electrodes configured to form an active volume of the component,
- wherein the active volume is not arranged centrally over the width of the component,
- wherein owing to the non-central arrangement of the active volume, a thermal time constant of the component is reduced,
- wherein the active volume is formed either by
- (i) overlap regions of adjacent inner electrodes of opposite polarity, wherein inner electrodes that are adjacent to one another in a stacking direction overlap with one another in at least one overlap region and the active volume of the component is formed by the at least one overlap region of the inner electrodes, or
- (ii) a region which is situated between two inner electrodes of opposite polarity, wherein the two inner electrodes are arranged in the same plane and do not touch each other, wherein the region between the two inner electrodes forms the active volume of the component,
- wherein the active volume is arranged in a left-hand-side region, which extends from the first side face as far as a width of not more than 30% of the width, and/or in a right-hand-side region, which extends from the second side face as far as a width of at least 70% of the width,
- wherein, in the width direction, a central region, which is free of inner electrodes, is arranged between the left-hand-side region and the right-hand-side region and directly adjoins the left-hand-side region and the right-hand-side region in each case, and
- wherein the component is a ceramic multilayer component.
