a power module, the power module including a thermistor assembly, the thermistor assembly including:

a conductive layer including a trench;

a thermistor connected to the conductive layer and disposed across the trench; and

a first height control feature between the conductive layer and the thermistor.

2 . The system of claim 1 , wherein the thermistor assembly further comprises:

a solder layer between the conductive layer and the thermistor.

3 . The system of claim 1 , wherein the thermistor assembly further comprises:

a trench filling material in the trench.

4 . The system of claim 3 , wherein the first height control feature and the trench filling material include a same material.

5 . The system of claim 1 , wherein the first height control feature has a rounded shape.

6 . The system of claim 1 , wherein the first height control feature has a rectangle shape.

7 . The system of claim 1 , wherein the thermistor assembly further comprises:

a second height control feature between the conductive layer and the thermistor.

8 . The system of claim 7 , wherein the first height control feature and the second height control feature are a same size.

9 . The system of claim 2 , wherein the conductive layer includes copper and the solder layer includes one or more of a solder paste or a solder preform.

10 . The system of claim 2 , wherein the solder layer is printed on the conductive layer.

11 . The system of claim 1 , further comprising:

the battery configured to supply the DC power to the inverter; and

the motor configured to receive the AC power from the inverter to drive the motor, wherein the system is provided as a vehicle including the inverter, the battery, and the motor.

12 . A system comprising a thermistor assembly, the thermistor assembly including:

a conductive layer including a trench;

a thermistor connected to the conductive layer and disposed across the trench; and
