I am looking for this fuse and i have been told by a colleague that this fuse may be the one i’m looking for but before i order it please can you confirm there is a resistor inside this glass fuse.
Thank you for contacting Digi-Key , the fuse 0313.031HPX does not have a built in resistor like the one you have pictured above , although it does have a DC cold resistance of 430 ohms which looks like is the same value of the resistor in the one pictured above. Data sheet link below for the 0313.031HPX
We currently stock this product. Click here for F2525-ND (0313.031HXP). As Craig_2048 stated, this does have a cold resistance of 430 ohms which appears to match resistance in the photo.
I stand corrected I had the warehouse tech look at the parts and they do have an internal resistor just like the one you have . The data sheet does not show that though .
