How big a power supply needs to replace the capacitor [PDF]

6 FAQs about [How big a power supply needs to replace the capacitor]

Do electrolytic capacitors need to be replaced?

Generally its only electrolytic capacitors that need replacing, the most critical being the ones serving as filters in the power supply. Occasionally resistors that are stressed (like ones near the power tubes) can fail, and in some designs its a good idea to replace some of these with higher tolerance ones before they fail.

Should power supply filter capacitors be increased?

Increasing the value of power supply filter capacitors is generally okay, within reason. Too large an increase (even if it fits physically) may stress the transformer and rectifiers due to the huge current in-rush on start-up. Capacitors in speaker crossovers should remain the same nominal capacitance to avoid changing the crossover points.

Which values should be followed when replacing capacitors?

Hi, in general, when replacing capacitors, which values (be it capacitance, voltage, ripple current, leak current, ESR, e.t.c.) must be followed and which ones are ok to be different? This mostly depends on the particular circuit. However, if the part will fit physically, a higher voltage rating will be ok. and lower leakage is ok.

How to choose a smoothing capacitor?

The power rating and the capacitance are two important aspects to be considered while selecting the smoothing capacitor. The power rating must be greater than the off load output voltage of the power supply.

Can you replace a capacitor with a higher value?

In many cases, replacing a capacitor with a higher or lower value can make the circuit perform differently or better than before. However, keep in mind that increasing the capacitance may affect the resonant frequency of LC circuits and also increase their current draw. Can I use a 25V capacitor instead of 35v?

Why is a bigger capacitor better than a smaller one?

A bigger capacitor presents more area with which to dissipate heat to the surrounding air and can therefore tolerate more internal power dissipation without a destructive temperature rise. Consequently, the capacity ( μ F) and voltage rating are not enough by themselves to identify a suitable replacement in these cases.
