I have a simple digital multimeter in which a fast tube fuse, rated at 0.1A and 250V is soldered directly to the plate.
Now, recently this fuse blowed and I have to replace it. Because I don't want to mess with soldering every time a fuse is blown (and there is no place for a fuse holder), I was thinking about replacing the tube fuse with the polymer fuse rated at 0.1A and 60V (RXEF010). Is this reasonable?
There are two possible concerns:
- Will a polymer fuse break the circuit as fast as a tube fuse?
- Is there a large ohmic difference between two fuses? Voltage and current ratings suggest that the polymer fuse has four times smaller resistance, which should be advantageous.
Anyone has any idea about these issues?
