Why Choose the Mersen Y084362 Miniature Semiconductor Fuse?
The Mersen Y084362 is a high-performance 6.3 × 32 mm high-speed semiconductor fuse designed to protect sensitive electronic components and power-semiconductor devices against overcurrent and short-circuit faults. Also identified by catalogue number MI6FA40V5, it has a rated current of 5 A and a rated voltage of 400 V AC.
Part of the Mersen FA/FB miniature semiconductor fuse series, the Y084362 features a very fast-acting characteristic that helps limit the electrical energy transferred to protected components during a fault. This rapid interruption supports improved protection for rectifiers, power supplies, converters and industrial control equipment.
The Y084362 is manufactured with a durable ceramic body and nickel-plated ferrule terminals for clip mounting in compatible fuse holders. Its compact dimensions, high interrupting capacity and low let-through energy make it suitable for demanding industrial electronics and OEM equipment.
