Littelfuse 0.33 A Resettable Fuse 240V DC PolySwitch PPTC Radial Lead LVR033K

Littelfuse LVR033K is a 0.33 A resettable fuse designed for DC line-voltage protection up to 240V. It utilizes PolySwitch polymeric positive temperature coefficient (PPTC) technology to provide reliable circuit protection by limiting current during overloads and short circuits.

This radial lead fuse features a compact form factor with dimensions of 11.4mm length, 19mm height, and 3.8mm width, optimized for printed circuit board (PCB) integration. It has a hold current of 0.33 A and a maximum current rating of 4.5 A, with a fast time-to-trip of about 21 seconds to react promptly to fault conditions.

The device dissipates up to 1.7 watts power safely while protecting circuits within an operating temperature range from -40°C to 60°C, making it suitable for diverse environments. Its resistance ranges from a minimum of 0.77 Ω to a maximum of 2.6 Ω, allowing low-resistance operation under normal conditions.

Engineered for maintenance-free service without fuse holders, the fuse automatically resets thousands of times, improving system uptime and reducing replacement costs. It is certified by UL, TUV, RoHS, and CSA, ensuring compliance with international safety and environmental standards.

LVR033K resettable fuses are commonly used in medical devices, electric motors, power supplies, fans, security and fire alarms, test equipment, transformers, USB hubs, and peripherals, providing proficient protection from excessive current surges and overtemperature faults.

Resets automatically thousands of times without the need for fuse replacement. Rated for line voltages up to 240V DC and currents up to 4.5 A. Compact radial lead configuration suitable for PCB mounting. Fast response time with approximately 21 seconds time-to-trip to prevent circuit damage.

Compliance with UL, TUV, RoHS, and CSA standards for safety and environmental considerations. Wide operating temperature range from -40°C to 60°C for diverse industrial applications. Low resistance ensures minimal voltage drop and efficient circuit operation.

Maintenance-free design eliminates the need for fuse holders. Ideal for applications in medical equipment, motors, fans, security systems, and computing peripherals.
