Overview of 2920L100PR by Littelfuse Inc.
The 2920L100PR by Littelfuse Inc. is a surface mount PTC resettable fuse, housed in a 2920 (also known as 2921) rectangular chip package. As a Non-linear Resistor, it’s designed to temporarily increase its resistance significantly in response to excessive current, providing overcurrent protection. Once the abnormal current ceases and normal conditions are restored, the fuse automatically resets itself to the low-resistance state, allowing the current to flow again. This part is fully compliant with RoHS regulations, verifying it doesn’t contain restricted hazardous materials.
Key attributes of the 2920L100PR include its operating voltage of 33V, an operating current of 1.1A, and a resistance of 0.12 Ohms, making it well-suited for protecting circuits by limiting excessive current. It operates effectively across a broad temperature range from -40°C to +85°C, and its surface-mount design, with a package size of 7.98mm in length, 5.44mm in width, and 1mm in height, makes it ideal for compact electronic applications. The part utilizes a matte tin terminal finish and is compatible with automated surface mount assembly processes, ensuring ease of integration into PCB designs.
