| RC filters | LC filters |
|---|---|
| The RC filter is only useful for small load currents. | The LC filters are useful for heavy load currents. |
| More power dissipated in RC filter. | Less power dissipated in LC filter. |
| It has poor voltage regulation. | It has good voltage regulation. |
| It is cheaper. | It is costlier. |
| It also requires ventilation to conduct away the heat produced in the resistor. | It does not require any ventilation because the heat is not produced in the inductor. |
| It has high ripple factor. | It has low ripple factor. |
| RC is fine for filtering low power signals. | LC is fine for filtering high power signals. |
