- Trip Current: 3.7A
- Voltage Rating: 60V
- Operating Temperature Range: -40°C to 85°C
- Maximum Time-to-Trip: 20 seconds at 200% of rated current
Detailed Pin Configuration
The MF-R185-2-99 features two terminals for connection within the circuit. The pin configuration is as follows: - Pin 1: Input/Anode - Pin 2: Output/Cathode
Functional Features
- Overcurrent Protection: Limits current flow during fault conditions.
- Automatic Reset: Restores normal operation after fault clearance.
- Fast Response: Quickly reacts to overcurrent events to prevent damage to the circuit.
Advantages and Disadvantages
Advantages
- Reusability: Can be reset multiple times, unlike traditional fuses.
- Space-Saving: Compact design allows for efficient use of board space.
