0805L050WR

The 0805L050WR is a surface-mount PolySwitch resettable fuse manufactured by Littelfuse. This component is designed to protect electrical circuits against overcurrent conditions, which can potentially cause damage or failure. The "0805" refers to the standard package size of the component, measuring approximately 0.08 inches by 0.05 inches. The "050" indicates its hold current, which is 0.5 amps, meaning it will allow this current to pass under normal operating conditions. The "WR" signifies that it features a wider resistance range or specific material characteristics suited to certain applications.
PolySwitch fuses are made from a polymeric positive temperature coefficient (PPTC) material. When excessive current flows through it, the material heats up and expands, increasing resistance and effectively limiting the current flow. Once the fault is cleared and the component cools down, it resets itself, allowing current to flow normally again. This makes the 0805L050WR ideal for applications where consistent protection and resettable functionality are required, such as in telecommunications, consumer electronics, and automotive applications.

3. Voltage Rating: It supports a maximum operating voltage of 6V, suitable for low-voltage applications.
4. Resistance: The initial resistance typically ranges between 0.3 to 1.2 ohms, with a post-trip resistance of up to 3 ohms.
5. Temperature Range: It operates effectively over a temperature range of -40°C to +85°C, providing flexibility in various environmental conditions.
6. Resettable Functionality: The PTC characteristic allows it to reset after a fault condition is cleared, providing overcurrent protection without the need for component replacement.
7. Applications: Commonly used in consumer electronics, telecommunications, and computer peripherals for safeguarding against overcurrent conditions.
These features make the 0805L050WR a reliable choice for protecting circuits in compact and sensitive electronic devices.

The 0805L050WR is a surface-mount Polymeric Positive Temperature Coefficient (PPTC) resettable fuse, commonly used for overcurrent protection in electronic circuits. It is part of the 0805 package series, which is a standard surface-mount package size with dimensions of approximately 2.0 mm x 1.2 mm. This component typically has two pins or terminals, designed for easy integration into printed circuit boards (PCBs).
The primary function of the 0805L050WR is to protect electronic circuits from overcurrent conditions by limiting the flow of excessive current. In normal operation, it allows current to pass through with low resistance. When an overcurrent condition occurs, the device heats up and increases its resistance significantly, thus reducing the current flow to protect the circuit. Once the fault is cleared and the device cools down, it resets itself to its low-resistance state, allowing normal current flow to resume. This self-resetting capability makes PPTCs like the 0805L050WR ideal for applications requiring maintenance-free overcurrent protection.
