Bourns 2.5 A Resettable Fuse, 30V, Radial Leaded MF-R250

Bourns MF-R250 is a high-quality resettable fuse designed to protect electrical circuits from excessive current conditions. This fuse features a nominal hold current of 2.5 amps and a trip current of 5 amps, making it ideal for safeguarding sensitive electronic components and devices. It operates at a maximum voltage of 30 volts DC, suitable for use in low voltage electronic and electrical equipment.

The device employs a radial leaded design, which facilitates easy installation onto printed circuit boards. The compact dimensions (12 mm length, 18.3 mm height, and 3 mm width) enable integration in space-constrained applications. The fuse's body is made from a cured, flame retardant epoxy polymer material that complies with UL 94V-0 standards, ensuring safety and reliability under operating stresses.

In the event of an electrical overload or short circuit, the MF-R250 rapidly changes to a high resistance state, interrupting the current flow. Once the fault condition is removed and power is restored, the fuse automatically resets to its low resistance state, providing maintenance-free operation. This resettable capability makes it cost-effective and reduces downtime by avoiding the need for fuse replacement.

This fuse supports a maximum current rating of 40A and dissipates up to 1.2 watts of power. It operates reliably within an ambient temperature range from -40°C to 85°C, making it suitable for a wide range of industrial, automotive, instrumentation, security systems, computing peripherals, medical equipment, and telecommunications applications.

The radial lead orientation with a lead diameter of 0.81 mm allows for secure soldering and optimal electrical contact. The Bourns MF-R250 fuse series is UL, CSA, and TUV approved, ensuring compliance with international safety standards.

Features a trip current of 5A for effective overcurrent protection. Compact design with 12mm length and 18.3mm height for PCB mounting. Flame retardant epoxy polymer construction meets UL 94V-0 requirements. Automatically resets after fault conditions, eliminating fuse replacement.
