Electrical Specifications by Item
1. Measured at 10% of rated current, 25ºC.
2. Measured at rated voltage.
The 435 Series are fast-acting surface mount thin-film
fuses. Their ultra-small size (0402 size) makes them ideal for
secondary protection of circuits used in space constrained
applications such as hand-held portable electronic devices.
This series is 100% lead-free and meet the requirements of
the RoHS directive. New Halogen-Free 435 Series fuses are
available–to order use the “HF” suffix. See Part Numbering
section for additional information.
Applications
• Cell phones
• Battery packs
• Digital cameras
• DVD players
• Hard disk drives.
Secondary protection for space constrained applications
such as:
