250V is the max voltage rating of these fuses. As long as the voltage is lower than 250V you can use these fuses.

300mA (milliamps) is 0.3 amps. Unfortunately we do not have a fuse with that low of a value.

You should be using one that is the correct physical size and with the correct amperage, and either a slow or fast blow. These fuses are 0.25" x 1.25" and we offer smaller ones here: https://www.amplifiedparts.com/products/fuse-slo-blo-5mm-x-20mm. We only sell at 6.25 amp fuse and do not carry a 6 amp.

The highest amperage we carry for fuses is 6.25 amp. We would not advise using this fuse in your amp if it calls for a 6.3 amp fuse. These fuses are imported.

We do not have sufficient cross reference materials to verify what fuse is needed for your amp. We recommend you consult a professional repair tech.

I used the 1 amp fuse for my 5f1 clone, it does the job. Fast shipping and a good price!
