Reliable Protection for Sensitive Electronic Circuits
Semiconductor miniature fuses protect electronic components by interrupting sustained overcurrents before excessive heat or electrical stress damages connected equipment. Selecting the correct fuse characteristic is important because many electronic devices draw a temporary surge when energised.
The super time-delay characteristic of the Mersen S090797 helps prevent nuisance operation during short-duration inrush currents while remaining responsive to persistent overload conditions. This makes it suitable for control apparatus, semiconductor circuits and other electronic systems requiring stable, dependable protection.
Typical Applications
- Semiconductor device protection.
- Industrial electronic control equipment.
- Automation and process control systems.
- Electronic power supplies.
- Control boards and instrumentation.
- OEM machinery and electronic assemblies.
