关于 Littelfuse INC /de
Littelfuse, Inc. 是一家在美国上市的工业技术公司，在纳斯达克交易，股票代码为LFUS，因此对于关注美国股票的投资者来说，它是一个美国公开市场名称。对于讲法语的投资者来说，该公司作为一家高度专业化的工业特许经营企业而脱颖而出，专注于电气保护、电源控制和传感。Littelfuse 成立于1927年，围绕电路保护和关键可靠性组件建立了悠久的运营历史。公司总部位于美国伊利诺伊州芝加哥，业务遍及全球20多个国家，服务于工业、交通和电子终端市场的广泛客户群。([sec.gov](https://www.sec.gov/Archives/edgar/data/889331/000114036125008766/ny20037073x4_ars.pdf)) Littelfuse 通过三个部门报告其业务：电子、交通和工业。这种结构反映了技术产品的多元化组合，而非单一的终端市场。电子部门包括熔断器和熔断器附件、PTC可复位熔断器、机电开关、互连解决方案、ESD抑制器、压敏电阻、基于簧片开关的磁传感、气体放电管、TVS二极管、晶闸管、MOSFET和相关半导体器件。交通部门涵盖用于乘用车和商用车的betway体育app，而工业部门则涉及自动化、可再生能源、储能、HVAC、电机驱动器、电源和更广泛的电气安全需求相关的应用。Littelfuse 总共服务超过100,000个终端客户，其大部分销售额来自美国以外；在2024财年，约63%的净销售额来自美国以外的客户。([sec.gov](https://www.sec.gov/Archives/edgar/data/889331/000114036125008766/ny20037073x4_ars.pdf)) 从竞争角度来看，Littelfuse 在关键任务组件领域占据了一个有吸引力的利基市场。其设备嵌入到对安全性、正常运行时间、小型化和合规性至关重要的系统中，这往往支持重复的设计中标和转换成本。公司的业务与电气化、能源效率、自动化、连接性、人工智能基础设施和更安全的移动性等长期世俗趋势紧密结合。这使得Littelfuse 不仅仅是一个简单的熔断器制造商：它正日益成为复杂电气系统的赋能技术提供商。([sec.gov](https://www.sec.gov/Archives/edgar/data/889331/000114036125008766/ny20037073x4_ars.pdf)) 最近的发展对投资案例很重要。2024年12月，Littelfuse 完成了对德国多特蒙德200mm晶圆厂的收购，增强了其功率半导体能力。2025年10月，它宣布收购 Basler Electric，并于2025年12月完成交易，扩大了公司在电网和公用事业基础设施、发电和数据中心相关应用领域的业务。公司还公布了2025年全年业绩，显示收入增长和利润率扩张，同时指出与半导体betway体育app业务相关的非现金商誉减值。在2025年和2026年初，Littelfuse 继续推出高压熔断器、汽车电流传感器、TVS二极管、MOSFET和固态继电器等新betway体育app，凸显了活跃的创新betway体育app线。([investor.littelfuse.com](https://investor.littelfuse.com/news/news-details/2024/Littelfuse-Completes-Acquisition-of-the-200mm-Wafer-Fab-Located-in-Dortmund-Germany/default.aspx?utm_source=openai))
