WebMay 5, 2024 · The point about a poly fuse is that it resets itself so it does need replcing. In fact they are very slow to blow when the current is just over the trip point and they are more of a protection against shorts. I don't think you will find a 250 mA one but if you do it would be too close to a normal load and might blow after an hour or so. WebJan 3, 2006 · FIG. 1 shows a schematic diagram of a conventional poly fuse trimming circuit.
