Overview of 2920L075DR by Littelfuse Inc.
The 2920L075DR by Littelfuse Inc. is a PTC (Positive Temperature Coefficient) resettable fuse with a resistance of 1 ohm and designed for surface mount applications, belonging to the Polyfuse 2920L Series. This component is characteristic of Non-linear Resistors which fundamentally serve as circuit protection devices. It features a holding current of 750mA, a tripping current of 1.5A, and a voltage rating of 30VDC. The operating temperature range of this resettable fuse spans from -40°C to 85°C, making it suitable for various environmental conditions.
The device’s packaging is characterized as CHIP in a rectangular shape, with a package length of 7.98 mm, width of 5.44 mm, and height of 1.25 mm. For surface mounting, it utilizes a matte tin terminal finish and provides dual-ended, wraparound terminal placement. Notably, this component adheres to environmental and safety standards such as RoHS, REACH compliance, and is certified under reference standards like cUL, TUV, and UL.
Industry Applications for 2920L075DR
The 2920L075DR could potentially serve a variety of industries due to its specifications and properties particularly suiting applications where durable and reliable overcurrent protection is critical. Here are some possible industry applications:
- Consumer Electronics: Devices such as smartphones, PCs, and TVs, which require protection against current surges and overheating, could potentially utilize such PTC fuses. The component’s fast tripping current feature and small size make it suitable for compact electronic assemblies.
- Industrial Automation: In automated systems and heavy machinery which may experience sudden changes in current, the resettable feature and the component’s robust operating temperature range may provide necessary reliability and functionality.
- Telecommunications: Network equipment such as routers, modems, and switches can benefit from such fuses to prevent damage due to power surges, thereby ensuring sustained service and connectivity.
- Automotive: Given the harsh environments often associated with automotive applications, and assuming these components were to satisfy standards like AEC-Q100, this type of PTC fuse might be suitable for applications within vehicle electronic subsystems to protect against fluctuations caused by the alternator or other power sources.
Note that these potential industry applications are only conceptual/illustrative and require detailed analysis and verification by engineering and design teams for adherence to industry standards and specific application requirements.
