CERmaJump: Aluminum Nitride Thermal Jumpers (AlN)
Price range: €0.40 through €7.99
Use your ground plane to cool your hot components. Connect your hot component nets thermally with other circuit parts to reduce the temperature without adding any other cooling.
Thermal jumpers in Aluminum Nitride. Select your footprint below. We can change our design to meet your requirements if you need a custom footprint or thickness. Please get in touch with us.
Description
Thermal management is one of the bigger issues with the increasing amount of high power and smaller PCB applications. Keeping your electronics cool is essential to guarantee their correct and efficient working. To help you manage your projects’ thermal properties we designed thermal jumpers in AlN ceramic.
AlN ceramics are not only the best material to conduct heat, with a thermal conductivity of 170W/mK, but they also feature minimal capacitance.
The electrically isolated thermal jumpers have copper terminals that are finished with a nickel gold layer to ensure easy solderability and oxidation resistance.
Specifications:
- Material: Aluminum Nitride (170 W/mK)
- Conductor: Copper (Cu – 35um / 1oz)
- Surface finish: electroless nickel immersion gold (ENIG) (the nickel gold layer ensures easy solderability and oxidation resistance)
- Thermal expansion (CTE): 2 ~ 3 ppm/°C
- Thermal conductivity: >170 W/mK at 20°C
Typical applications:
- High-power LED and laser modules
- Power Electronics
- High-density circuits

Tests were conducted to show the effectiveness of the thermal jumpers. The temperature was reduced by up to 35°C(!), as shown by the black line in the graph on the right.
More information on thermal effectiveness can be found in our case study and the datasheet.
