Video Transcript
You can use a capacitor to block DC and let AC pass, you can use a filter to keep your signal and remove the noise, and now you can use Bourns’ BTJ Series SMD thermal jumper chip to extract heat without messing up your circuit design. The BTJ series thermal jumpers feature an aluminum nitride construction for efficient thermal conductivity while maintaining high electrical isolation. With thermal resistance as low as 4°C/W and operation up to 155°C, these thermal jumpers can effectively move heat from a component into a PCB heatsink, reducing component temperature and improving system reliability. They’re available in sizes from 0603 to 2512 including standard and long-side terminations, have a 1.5kVac to 5kVac dielectric withstand voltage for effective isolation, and the capacitance ranges from 0.07pF to 26pF for minimal impact on the circuit.
