Littelfuse TR5 372 Series Time Delay Radial Leaded PCB Fuse - 1

The Littelfuse TR5 372 Series offers a compact and reliable solution for protecting printed circuit boards (PCBs) in demanding electronic applications. These sub-miniature, radial-leaded fuses are designed to IEC 60127-3 standards and feature a sophisticated time-delay characteristic, allowing them to withstand temporary current surges without blowing unnecessarily. This makes them perfect for safeguarding circuits that experience high inrush currents during startup, such as those found in power supplies, motors, and transformers.

Their robust construction includes a shock-safe and vibration-resistant casing, ensuring stable performance in industrial and other challenging environments. The radial leaded design offers flexible installation: the fuse can be soldered directly onto the PCB for a permanent, space-saving connection or plugged into a compatible two-pin socket for easy replacement, facilitating maintenance and service. With an internal resistance, the fuse provides efficient performance while minimising power loss.

These fuses are internationally recognised, carrying approvals from key standards bodies including UL, VDE, PSE/JET, and CCC, confirming their safety and suitability for global markets. They are available with a choice of breaking capacities (35A, 40A, or 50A) to match the fault current levels of different applications. The operating temperature range of -40°C to 85°C ensures reliable performance in both extreme cold and hot conditions, making them a versatile choice for a wide range of electronic equipment.
