Abstract
In an embodiment a sensor element includes a carrier having an electrically insulating material, a top side and a bottom side, an NTC thermistor arranged on the top side of the carrier and at least two first electrodes configured for electrically contacting the sensor element, wherein the first electrodes are arranged on the top side of the carrier, wherein the sensor element is configured to measure a temperature, and wherein the sensor element is configured for direct integration in an electrically insulating manner.
Claims23
A sensor element comprising:
- a carrier comprising an electrically insulating material, a top side and a bottom side;
- an NTC thermistor arranged on the top side of the carrier;
- at least two first electrodes arranged on the top side of the carrier,
- wherein a respective one of the first electrodes comprises a first area configured for electrically contacting the sensor element by a wire bonding or soldering,
- wherein the respective one comprises a second area configured for electrically contacting the NTC thermistor by soldering,
- wherein the first area and the second area are interconnected by a web-shaped connecting area;
- at least one second electrode arranged over an entire surface on the bottom side of the carrier,
- wherein the second electrode is directly applicable to a conductor path of a power module using conventional assembly and connection technology;
- and
- a protective layer arranged at least around the NTC thermistor,
- wherein the protective layer completely envelops the NTC thermistor and comprises a polymer,
- wherein the NTC thermistor is an SMD NTC thermistor,
- wherein the sensor element is configured for direct integration in an electrically insulating manner, and
- wherein the sensor element is configured to measure a temperature.
