Dependable Protection for Sensitive Electronic Circuits
Miniature fuses protect electrical and electronic equipment by interrupting the circuit when current remains above the fuse’s designed operating threshold. This helps prevent excessive heat and electrical damage from affecting sensitive components, wiring and connected apparatus.
The super-slow operating characteristic of the Mersen B090805 makes it particularly useful in circuits that experience temporary inrush currents during normal operation. The fuse allows these brief surges to pass while remaining capable of disconnecting sustained overloads in properly coordinated applications.
Typical Applications
- Semiconductor equipment and electronic assemblies.
- Industrial control and automation apparatus.
- Electronic power supply circuits.
- Control boards and sensitive electronic components.
- Instrumentation and monitoring equipment.
- Low-voltage circuits with temporary inrush currents.
