Wickmann 0.75 A Radial Lead Resettable Fuse 72 V AC/DC 40A Current Rating RF2569-000

Wickmann RF2569-000 resettable fuse is a high-quality 0.75 A radial lead PPTC device rated for 72 V AC and DC voltage applications, designed for robust overcurrent protection in sensitive electronic circuits.

This resettable fuse features a trip current of 1.5 A with a trip time of approximately 6.3 seconds, providing reliable circuit interruption during fault conditions while ensuring normal operation at currents below 0.75 A.

The compact form factor with dimensions of 10.2 mm length, 15.2 mm height, and 3 mm width makes it suitable for dense electronic assemblies where space is limited.

With a minimum resistance of 0.25 Ω and a maximum resistance of 600 mΩ, the fuse maintains circuit stability and reduces voltage drop. It effectively dissipates power up to 0.92 W, supporting safe operation within its thermal limits.

The device is engineered to operate reliably in a wide temperature range from -40°C up to 85°C, making it suitable for various industrial and commercial environments. RoHS, TUV, CSA, and UL compliance certify its adherence to international safety and environmental standards.

Applications include satellite video receivers, industrial control systems, transformers, computer motherboards, modems, USB hubs and ports, battery packs, phones, fax machines, printers, and both analog and digital line cards.
