Answer

Below you can find a series of capacitor combinations to replace a 378 µF capacitor.

Series Combinations:

For two capacitors in series, the total capacitance is calculated as:

\(C_{total} = \frac{1}{\frac{1}{C_1} + \frac{1}{C_2}}\)

For example, with 460 µF + 2200 µF in series = 380.45 µF (error: 0.65%)

\(C_{total} = \frac{1}{\frac{1}{460} + \frac{1}{2200}} \approx 380.45 \mu F\)

Mixed Combinations:

For a mixed combination, first calculate the series capacitance:

\(C_{series} = \frac{1}{\frac{1}{C_1} + \frac{1}{C_2}}\)

Then, place this combination in parallel with the third capacitor:

\(C_{total} = C_{series} + C_3\)

For example, with 180 µF + 270 µF in series with 270 µF in parallel = 378 µF (exact)

\(C_{series} = \frac{1}{\frac{1}{180} + \frac{1}{270}} \approx 108 \mu F\)

\(C_{total} = 108 \mu F + 270 \mu F \approx 378 \mu F\)

How Does The Capacitor Combination or Replacement Calculator Works

Introduction

Our calculator becomes vital when one wants to determine an appropriate set of capacitors that can be paralleled together to obtain a specific equivalent capacitance. Our Capacitor Replacement Calculator comes with a straightforward interface, making it easy for learners and hobbyists to do series and parallel calculations for capacitance in circuits.

What is Equivalent Capacitance?

When capacitors are connected in series, parallel, or in any other combination, they will combine to create an overall or equivalent capacitance. In ideal conditions, without the inclusion of other parameters, it works as a single capacitor.

Calculation Methods

The calculator operates by using an array of standard capacitor values, ranging from very small to large values. When you input the values of the equivalent capacitor, the calculator looks at all possible combinations of the standard values in the array to find the most accurate possible equivalent capacitance. Here's how it does it:

Series Combinations

How can I find total capacitance when I have a series combination? When capacitors are connected in series, it is obtained by adding reciprocal values of all individual capacitors according to this formula:

\(C_{\text{total}} = \frac{1}{\left(\frac{1}{C_1} + \frac{1}{C_2} + \cdots + \frac{1}{C_n}\right)}\)

to find the value of the equivalent capacitor.

Parallel Combinations

How do I find the total capacitance of a circuit in parallel? All we need to do is sum up the individual capacitances. The calculator uses the formula:

\(C_{\text{total}} = C_1 + C_2 + \cdots + C_n\)

to find the value of the equivalent capacitance.

paralell capacitor picture

Mixed Combinations

For more complicated configurations, the calculator makes a combination of series and parallel connections. Firstly, it calculates the parallel capacitances and then considers the result as a single capacitor in a series combination, or vice versa, to achieve the targeted capacitance.

Example

For example, if you want to have a capacitor with a total capacitance of 10 µF, the calculator could suggest combining a 5 µF and another 5 µF capacitor in parallel or combining two 20 µF capacitors in series. It also can find a mixed configuration of a 4 µF + 4 µF in series with 8 µF in parallel.

What are the basic rules when replacing a capacitator?

What are the basic rules when replacing a capacitator?

While changing a capacitor, it should be ensured that some conditions are met for it to work well in circuitry. These fundamental rules are:

  • Capacitance Value: The replacement capacitor should have a similar capacitance value to the original one or only differ within an acceptable tolerance limit.
  • Physical Size and Lead Spacing: The available space and PCB layout should match the physical size and lead spacing of the replacement capacitor.
  • Voltage Rating:The voltage rating of any substitute capacitor has to be either equal to or above that of the original capacitor's voltage rating.
  • Type of Capacitor: The type (e.g., ceramic, electrolytic, film) should meet the requirements of the particular circuit.

Why Use Equivalent Capacitors in Series and Parallel Combination?

Series And Parallel Combinations Of Capacitors Can Have Following Benefits:

  • Custom Capacitance Values: Get specific capacitance values that you have tailored to individual circuit requirements.
  • Improved Performance: It is possible to increase component reliability, longevity by reducing ESR or increasing voltage rating in a series combination.
  • Availability: Easier to find standard capacitor values that can be combined to meet the specific capacitance value.

Why Use Our Capacitor Combination or Replacement Calculator?

Our powerful calculator will help you save time and effort while working on your electronics projects. It will help you quickly build an equivalent capacitor from a list of standard or frequently used capacitance values.
