Overview of SMD185F-2 by Littelfuse Inc.
The SMD185F-2 by Littelfuse Inc. is a polymeric positive temperature coefficient (PPTC) resettable fuse that is specifically designed for overcurrent protection in electronic circuits. This resettable fuse is available in a surface mount (SMD) chip format with a 1206 footprint, which is compatible with standard automated assembly processes. It is ROHS compliant, demonstrating adherence to stringent environmental standards regarding the restriction of hazardous substances.
Key specifications of the SMD185F-2 include a holding current of 1.85A and a tripping current of 3.6A, making it suitable for applications with moderate current requirements. The fuse can handle a maximum voltage of 33Vdc. With an operating temperature range from -40°C to 85°C, it ensures versatile application potential across varied environmental conditions. The fuse body follows a standard rectangular package shape with a resistance of 0.065 Ω, and uses a surface mount technology (SMT) for mounting on printed circuit boards (PCBs).
Industry Applications for SMD185F-2
The SMD185F-2 could be particularly useful in several high-tech industry applications where reliable overcurrent protection is critical. Here are a few illustrative examples:
