Solution Guide: Replacing Electrolytic Capacitor with MLCC

Replacing electrolytic capacitors with MLCCs offers various benefits such as space reduction due to smaller size and lower profile, reduced ripple voltage due to low ESR, and improved reliability due to reduced self-heating. On the other hand, low ESR, which is an advantage of MLCCs, can sometimes lead to abnormal oscillation or anti-resonance.

6 FAQs about [What is the basis for capacitor replacement ]

Is it necessary to replace a capacitor with an exact replacement?

No, it is not necessary to replace a capacitor with an exact replacement. 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 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?

How do I find a replacement capacitor?

Now we will start searching for replacement capacitors. First, go to the website of your electric components distributor and go to the Aluminum Electrolytic Capacitors section. Narrow the search by entering the capacitance (uF) and voltage (V) values of the old capacitor. You may also want to check the box to only show components that are in stock.

How do you replace electrolytic capacitors in a circuit board?

Here are some fundamental rules for replacing electrolytic capacitors in circuit boards. Replace with exact type if available. Replace with capacitor that has the same capacitance (uF – microfarad) as the original. Replace with capacitor that has the same voltage rating or higher. Use higher temperature capacitors when possible (105c).

How much does a capacitor replacement cost?

On average, the cost of capacitor replacement typically ranges from $100 to $300, including both the cost of the capacitor itself and the labor for installation. However, this is a general estimate, and actual costs may vary based on individual circumstances. Additional factors that can influence the cost of capacitor replacement include:

What should I know before replacing a capacitor?

Before replacing a capacitor, make sure that it has a higher voltage rating than the original one. A lower voltage rating can lead to poor performance and even component failure over time due to the increased stress.
