*Current is limited to less than 50A at 32V due to internal fuse resistance.
For F1206B and F0805B at -55°C is 107% of rating, at +25°C 100% of rating,
at +85°C 93% of rating, at +125°C 90% of rating. For F0805B 2.50A and 3.00A
at +85°C 90% of rating, at +125°C 90% of rating.
Interrupting rating: 50A.
Insulation resistance: >20MΩ guaranteed (after fusing at rated voltage).
For F0612D at -55°C 107% of rating, at +25°C 100% of rating, at +85°C 80% of
rating, at +125°C 75% of rating.
