+ | Input circuit: | ||
+ | * Fuse 2,5A AL - of course it survices (2,5A is too much for this device, rated as 0,15A) | ||
+ | * Filters: 20 Ohm SMD resistor and ferrite coil with not so thick wire - both broken (2x R and 2x L). Ferrite coil value is not known. Other power line adapters are using 47uH ferrite | ||
+ | * Quite big sized varistor - it saves shole device shorting the overvoltage. | ||
+ | * Model 471KD10J, for 300V AC voltage operation, 1mA @ 470V. Diameter 12mm, thickness 4mm | ||
+ | * Replaced | ||
