L1: Choke coil
Coil for switching regulator. The inductance should be 820µH,
the rated direct current should be 0.42A or above
in order to prevent excessive heat generation or oscillation.
R1: Noise reduction
resistor
10 to 22Ω 1/4W
The ideal value can be determined through actual testing.
ZNR: Varistor
A varistor must be used to protect against lightning surges and static electricity.
