Overview
The Littelfuse 2920L200DR is a surface-mount Polymeric Positive Temperature Coefficient (PTC) resettable fuse designed for robust circuit protection. Its primary function is to limit fault current, automatically resetting once the fault is cleared. A critical design consideration for this device is its inherent resistance increase post-trip, which, while enabling reset, can introduce a voltage drop and power dissipation that must be accounted for in the system’s steady-state operation to prevent nuisance tripping or excessive heat generation.
Key Features
- Maximum Voltage Rating: 15V
- Hold Current (Ih): 2 A
- Trip Current (It): 4 A
- Maximum Fault Current: 40 A
- Initial Resistance (Ri): 50 mOhms (Min)
- Package: 2920 (7351 Metric), Concave (7.35mm x 5.12mm)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Overcurrent protection for low-voltage DC power supplies.
- Inrush current limiting for sensitive semiconductor devices.
- Fault isolation in battery management systems.
- Protection against short circuits in consumer electronics peripherals.
