The ACCU-GUARD fuse is based on thin-film
technologies. This technology provides a level
of control on the component electrical and
physical characteristic that is generally not
possible with standard fuse technologies. This
has allowed AVX to offer a device which is
designed for modern surface mount circuit
boards which require protection.
Features
• Accurate current rating/fusing characteristic
• Fast acting fuse (within 5 sec at I rated × 2)
• Rated Voltage : 32V, 63V
• Current Rating : 0.2A to 5.0A
• Insulation Resistance : >20MΩ
(after fusing at rated voltage)
Applications
• Computer
• Hard disc drives
•
Switching power supplies
• Telecommunication
