Replacement for 1A SMD fuses found on first gen PSone mainboards and GameBoy Color F1 / F2
Fuses usually marked with "20" or "S0"
PSone schematics specify 0.8A fuses but production hardware appears to use 1A fuses.
Later PSone consoles (1-679-335-82) use 0603 sized fuses. These won't fit those consoles.
