General procedure for replacing capacitors
General procedure for replacing capacitors (see below)

First of all, it is advisable to take lots of photos. From the wiring, from the circuit board, from the capacitors.
Electrolytic capacitors must be installed with the correct polarity; the negative pole is usually marked by a strip on the side of the housing.
It's good if you can see which way around the capacitor was installed, which you're holding between your fingers so that you can install the new one the right way round (in some cases you can't trust printed circuit boards, if they exist).

In individual cases, we recommend desoldering using desoldering wire and a desoldering suction pump. An electronic desoldering station with a heated suction gun would be best, but it is usually not worth purchasing for smaller projects.

First get an idea of the situation. Keep in mind that in the vast majority of cases, electrolytic capacitors were supplied with a higher voltage rating.

The value of the maximum permissible voltage (V) may be the same as that of the old capacitor, but may very well be higher and may never be smaller.


Voltage Capability

In 1987, due to Europe-wide harmonization, the mains voltage in some countries has been increased from 220V (198V-242V was possible) to 230V (207V-253V is possible since then).
This may only concern Europe, but similar is possible in countries with a 100-127V mains voltage with the same effect.

Due to the smoothening of the DC by electrolytic capacitors, which usually takes place immediately after the transformer and rectification, and with the DC voltage regulation only taking place afterwards, many such capacitors are now operated above the permissible voltage. The voltage capability was usually calculated very tightly due to the bigger size and higher price of caps with an increased one. This is particularly noticeable in Philips CD players, where the 16V caps in the power supply now run at 16V or above.

It is therefore strongly recommended that devices that can be switched from 220 to 240V (or from 100/110/120 one step increasing) be switched or soldered accordingly if you live in an area such a voltage increasement has taken place. Unfortunately, some do not offer this option; safety is then installed with an increased voltage resistance of the electrolytic capacitors.

Capacitors have become smaller over time, so that size is no longer an exclusion criterion for voltage capability.

An example of this:

There are four different types of 47µF capacitors installed in your device:

47µF/10V,
47µF/25V,
47µF/35V and
47µF/50V.

We would supply you with the following replacement types:

2x 47µF/35V as replacement for 10V and 25V
2x 47µF/63V as replacement for 35V and 50V

Although the original comes with a 35V capacitor, a 63V capacitor is supplied to increase the voltage resistance.


Temperature resistance

In the past, only capacitors were installed that had a temperature resistance of 85°C, as this corresponded to the state of electrolytic capacitor production at the time.

Today these can easily be replaced by ones with a temperature resistance of 105°C; Unfortunately, some capacitors on the world market are sometimes only available in 85°C versions.

A set may therefore also contain some capacitors that only have a temperature rating of 85°C, although we try to avoid this.

The value of the maximum permissible voltage (V) may match that of the old capacitor, but it may very well be higher and must never be smaller.


Voltage Resistance

In 1987, due to harmonization across Europe, this meant an increase in mains voltage for some countries from 220V (198V-242V was possible) to approx. 230V (207V-253V has been possible since then).
In other countries with 100-130V mains voltage

Due to the filtering by electrolytic capacitors, which usually takes place immediately after the transformer and rectification, and the voltage regulation only occurring afterwards, many such capacitors are now operated above the permissible voltage, which was usually calculated very tightly due to the size (especially noticeable in Philips CD players).

Therefore, it is strongly recommended that devices that can be switched from 220 to 240V be switched or soldered accordingly. Unfortunately, some do not offer this option; in this case, safety is built in with an increased voltage resistance of the electrolytic capacitors.

47µF/50V.

A set may therefore also contain some capacitors that only have a temperature resistance of 85°C, even if we try to avoid this.
