Power Supply Filters With Low-Z Loads
Consider the LC filter circuit with a load impedance (single resistor) as shown below. We input some arbitrary voltage source, the L and C elements provide low pass filtering, and the

Home / What does LC filtering mean in a power adapter
An LC filter is a passive electronic circuit composed of inductors (L) and capacitors (C). These components work together to block or attenuate specific frequencies of electromagnetic interference while allowing desired signals to pass. One such solution is the LC filter —a reliable and widely-used configuration for attenuating unwanted noise in both power and signal lines. It is meant to prevent certain high-frequency AC components from passing through the circuit. simulate this circuit – Schematic created using CircuitLab How can I calculate that the value of L1 is correct and the filter values will not cause any issues to the power.
