High Voltage Explosion Proof 10.1x3.1mm 4012 Time Delay Surface Mount Fuse 1A 600VAC 350VDC
AOLITTEL NANO² SMD fuse is ideal for use in Datacom and telecom equipment
NANO² fuse is a fast-acting, very high current fuse designed for
high operating current applications. It offers enhanced thermal
cycling endurance (up to 500 cycles). Its low temperature rise and
excellent temperature stability characteristics make it ideal for
use in Datacom and telecom equipment like high-end servers, base
stations, power supplies, and blade computing applications. offers
high-amp circuit protection, ultra-high interrupting ratings (up to
500 A at 72 VDC), and a compact (10.1 mm x 3.12 mm x 3.12 mm)
surface-mount form factor to save board space.
Features & Benefits
High current rating (15 – 30 A) with higher voltage up to 100 VDC
Enhanced thermal cycling endurance
High melting i2t
Surface-mount fuse in a small footprint
Operating temperature range from -55°C to 125°C
Enables blade servers operating at higher power
Provides higher reliability in harsh thermal cycling conditions
Prevents nuisance tripping caused by transient surge during blade
server hot swapping
Allows for greater flexibility in fuse placement on slim blade
server boards
Ensures robust performance and reliable protection in ultra-high
ambient temperature working environments
