Littelfuse 422/422A 2410 Fast Acting SMD Thin Film Fuses

Littelfuse 422/422A 2410 Fast Acting SMD Thin Film Fuses are wire-in-air fuses designed to provide circuit protection to space-constrained applications. The automotive versions cater to compact auto electronics applications' secondary circuit protection needs. The wire-in-air design results in relatively high I2t in a 2410 size, excellent temperature stability, and performance reliability. These fuses are rated at 125V and 250V while operating within a -55°C to +125°C temperature range.
