Compare across fuse type, UL class, and voltage. Then cross-reference manufacturer part numbers to find suitable replacements.
Fuses for Sensitive Electronics
 |  |
Ferrule Cartridge Fuse | Knife-Blade Cartridge Fuse |
With a quicker response than standard fast-acting fuses, these fuses provide the best protection for sensitive electronics.
Breakthrough Current @ Voltage—Breakthrough current at voltage, labeled on the fuse as IR, is the maximum current that a fuse can safely stop in the event of a short circuit.
