All Amp Ohm Audio Capacitors are individually hand tested. Line on label denotes outer foil." Sound: The Amp Ohm PF-XAL-AL 630VDC is basically the same type as the above mentioned capacitor but with a higher voltage rating. The higher rating is obtained using thicker materials and therefore the 630VDC version (65mm) has a larger diameter than ...

The constant is typically on the order of .01 or less, and varies with the line of capacitor. For audio purposes, we don’t care how much leakage occurs when the amp is turned off. It can be significant for filter capacitors, however. Leakage current is proportional to the capacitance and voltage, and filter capacitors have a lot of both.

more robust than those in the audio-circuit, rated for at least 105°C or 125°C, not the 2 nd-rate 85°C capacitors we commonly find in widely-sold Chinese-made consumer equipment today. (And when lab-tested to their limits, we find many of those so-called 85°C Chinese capacitors actually fail at a real-world 45°C or 50°C.

Re: Audio amplifier output capacitor value. « Reply #2 on: June 07, 2020, 06:21:33 pm ». No magic about the output cap. It determines the bass cut off frequency and is easy to calculate. It's just a CR high pass filter. With a 4 ohm-loudspeaker and a 2200 uF cap, the cut off is at ~18 Hz. Caps in the feedback loop are normally for stability ...

Very nicely built amplifier, sounds sweet and powerfull, and the case is absolutely beautifull. 130W 8Ohm, 250W 4 Ohm. It has a 500 VA torrodial. The Cairn MEA 500 has from the factory 37600 µF of filtering capacitors.
What size capacitor do I need for a 1,000 watt amp? - Quora

Answer (1 of 3): Without going into elaborate calculations, a good rule of thumb is 1000 microfarads per amp of draw. You do need to decide how much headroom is needed and how much ripple is acceptable.

From our example circuit with a 12 Volt source, 1k Ohm resistor, and 1 micro-Farad capacitor, here is how the voltage across the capacitor looks plotted out while its charging up: Notice how 1 tau (RC) is equal to 0.001 seconds and by 5 * RC = 0.005 seconds, the voltage has reached steady state of 12 Volts.

I understand that amp outputs at 4 ohms. The front door speakers are 2 ohms and the dash tweeters (which are on the same channel) are 8 ohm with a 10uf capacitor. I was intending to replace the front door speaker with a 4 ohm speaker and the dash tweeter with a 4 ohm speaker (I will replace the amp at a later date).
