Description
The Littelfuse 37211000001 is a high-performance time-delay (slow-blow) radial leaded fuse from the TR5 372 series. Designed for direct PCB mounting, this fuse provides reliable, space-saving overcurrent protection for internal electronic circuits, power supplies, and control boards.
Engineered for robustness, the TR5 372 series is specifically designed to handle startup inrush currents without nuisance tripping, making it an excellent choice for electronics with inductive or capacitive loads. Its radial leaded design allows for efficient vertical mounting, ensuring a secure and stable connection on your circuit board while providing the professional-grade safety expected from Littelfuse components.
Key Features
- Time-Delay Reliability: Designed to endure temporary current surges during startup, preventing unnecessary fuse failure in sensitive applications.
- Space-Saving PCB Design: The compact radial leaded form factor is ideal for high-density circuit board layouts where board real estate is limited.
- High Performance: Engineered for consistent electrical characteristics and long-term durability in varied industrial and consumer electronics.
- Secure Mounting: Direct-to-board leads ensure a reliable, vibration-resistant connection suitable for industrial control environments.
