Littelfuse 0.12 A Resettable Fuse 240V DC PolySwitch PPTC Radial Lead LVR012K

Littelfuse LVR012K resettable fuse is a high-quality circuit protection device designed for electrical applications requiring reliable overcurrent and short-circuit defense. Featuring advanced PolySwitch polymeric positive temperature coefficient (PPTC) technology, this fuse automatically transitions from a low resistance state to a high resistance state when exposed to fault conditions such as overcurrent or overheating, thereby protecting sensitive components.

This device supports a voltage rating of 240V DC with a current hold rating of 0.12 A and a maximum operational current rating of 1.2 A. Its trip current is set at 300 mA with a rapid trip time of 15 seconds, enabling fast protective response. The fuse has compact dimensions of 8.3 mm length, 12.9 mm height, and 3.8 mm width, which allows it to fit readily into various circuit designs with radial lead orientation for ease of PCB mounting.

The operating temperature range spans from -40°C to 60°C, enabling it to function in diverse environmental conditions. With a power dissipation rating of 1W and resistance between 3 to 12 ohms, the LVR012K fuse ensures minimal power loss during normal use. It is RoHS compliant and carries certifications from TUV, UL, and CSA, ensuring adherence to stringent quality and safety standards.

Key industrial and commercial applications include protection in medical equipment, power supplies, motors, fans, fire and security alarm systems, test and measurement apparatus, and telecommunications hardware. The fuse provides maintenance-free, automatic reset capability, supporting thousands of reset cycles without replacement needs.
