Hi, I am getting two varistors with same voltage but different sizes: 1) 07d471k (small 07 series) 2) 20d471k (big 20 series). In the datasheet both has same "surge life time" but double surge current. The smaller varistor has already 50A surge current capability, which means it can blow fuse easily, then why I need to buy expensive 100A (big) surge varistor? Does the 'surge life' matter here? Ok, I am going to use it for a smart TV.
