Littelfuse Inc 494 Series Ultra-Small Fuses
Littelfuse's ultra-small thin-film devices are designed for secondary protection of circuits used in space-constrained applications
Littelfuse's 494 series fast-acting SMF is an ultra-small (0603 size) thin-film device designed for secondary protection of circuits used in space-constrained applications such as hand-held portable electronic devices. This series is 100% lead-free and meets the requirements of the RoHS directive.
Features
- Compatible with lead free solders and higher temperature profiles
- High-performance materials provide improved performance in elevated ambient temperature applications
- Marked on the top surface with a code to allow ampere rating identification without testing
- Low profile for height-sensitive applications
- Flat top surface for pick-and-place operations
