In order to calculate the values of the components in an L-section filter, we need to know the desired cutoff frequency. Without this information, it is not possible to determine the exact component values for the given L and C values.

However, I can provide you with a general procedure to calculate the component values for a desired cutoff frequency.

1. Determine the desired cutoff frequency, denoted as f_c.
2. Calculate the reactance of the inductor at the cutoff frequency using the formula: X_L = 2πf_cL.
3. Calculate the capacitance required to provide the desired reactance using the formula: X_C = 1/(2πf_cC).
4. Solve for the capacitance value using the formula: C = 1/(2πf_cX_C).
5. Solve for the inductance value using the formula: L = X_L/(2πf_c).

Using this procedure, you can calculate the exact component values for your desired cutoff frequency.

Note: The units used for frequency must be consistent (e.g., Hz) and the values of L and C should be in the same units (e.g., henry and farad).
