Pico fuse help?
Dear all..
By accident (short circuit) the pico fuse in my watt meter is blown . Could you help me to know value of ampere (ie: 250v 1/4 amp...) of this pico fuse. the dimension and color code in photo please. In the time waiting your help can I used glass fuse for replace .Thank you so much
That is not a fuse. That is a 61 Ohms 10% resistor. Pico fuses (when they have color bands) will only have 3 color bands. Otherwise their value is printed on them.

This Comment was made 3 years ago so things may have changed, (I'm going through the same troubles now figuring out if I have a slow-blow or fast-blow). In the post he said he just used a glass fuse and works fine? LittleFuse does have 4 banded Pico Fuses, however if it's the aprox size of a 1 Watt Resistor, I doubt it's a "Pico".

You need to explain why its getting hot. What are you doing with this meter ? You describe it as a watt meter ?

-I used this meter for measure power mini tesla coil
(30 to 80watts at 60v)
- Now my problem is solve (used glass fuse)
