Hi guys,  
we need to replace a Fuse in two USRP 1 and one USRP2 box.  
Can anybody tell me exactly which fuses we have to order?

Regards  
Johannes S.

We are located in Germany. Here in Farnell I can only find  
PANASONIC ERBRE4R00V  
would it be ok as well?

For USRP2 I can find  
COOPER BUSSMANN - TR/3216FF4-R - FUSE, SMD, 4A, 1206, FAST ACTING  
so this should be fine.

They broke over a longer period of time, mostly due to broken power  
supplies. But weren’t replaced because we didn’t need all of our  
USRP’s for quite some time.

Ok I just saw that in Germany I can only order  
COOPER BUSSMANN 3216FF4-R  
and not the version with TR  
otherwise I have to pay 20 Dollars additional to the normal shipping  
for the shipping from USA to ship some parts for 2-3 Dollars.  
So would that fuse be ok as well?

Ok we just decided to order from DigiKey and take the parts that you  
have mentioned.
