25W Power Amp: Can I Use a Thermal Pad?

AI Thread Summary
Using a generic thermal pad with the 25W power amp is generally acceptable, as any thermal pad or paste should work. However, it's important to consider the need for electrical isolation between the IC's metal casing and the heatsink, depending on the specific design. Proper thermal management is crucial for optimal performance and longevity of the amplifier. Users with experience in building amplifiers confirm that there should not be significant issues with using a thermal pad. Ensuring compatibility and safety in the design is essential for effective heat dissipation.

I'm using this 25W power amp:

And I'm wondering if I can use a generic thermal pad which I have laying around or if I need to use some other product.

I have built many amplifiers in my time (audio being among them). I don't believe you would have a problem.
Good luck.
 
Any thermal pad or paste will be OK, but depending on your design you might need electrical isolation between the IC's metal casing and the heatsink
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
