Littelfuse 1210L005WR 0.05 A Resettable Fuse 30V DC Surface Mount PTC 1210 Series

Littelfuse 1210L005WR is a 0.05 Ampere resettable fuse suitable for 30V DC circuits, using polyfuse PTC technology in a compact 1210 package size. It provides effective overcurrent protection by switching from a low resistance state to a high resistance state under fault conditions, with automatic reset once power is removed and the fault ceases.

This surface mount fuse measures 3.43mm in length, 2.8mm in width, and 1.25mm in height, featuring tin-plated copper terminals to ensure reliable solder connections. It operates effectively between -40°C and 85°C, rated for a power dissipation of 0.6W.

The fuse has a hold current rating of 0.05A and a trip current of 0.15A, with a rapid trip time of 1.5 seconds to protect delicate electronic components against short circuits and overloads efficiently. Its low minimum resistance of 3.6 Ω and maximum resistance of 50 Ω help maintain circuit integrity.

Thanks to its maintenance-free design, it can endure thousands of resetting cycles, making it highly durable for repeated fault events. The Littelfuse 1210L005WR is ideal for use in security systems, power supplies and transformers, automotive circuits, medical instruments, control systems, computers, audiovisual and telecommunications equipment.

This polyfuse is RoHS compliant, ensuring adherence to hazardous substance standards. Available supplied on reels to facilitate automated assembly and manufacturing efficiency. Small size allows for use in dense PCB layouts where space-saving is critical.
