Amphenol Corporation, commonly known as Amphenol, is an American producer of electronic and fiber optic connectors, cables, and interconnect systems. Founded in Chicago in 1932 by Arthur J. Schmitt as the American Phenolic Corporation, it is headquartered in Wallingford, Connecticut. Amphenol is a publicly traded company on the New York Stock Exchange under the ticker symbol APH. As of December 31, 2025, the company reported approximately 170,000 employees. Its revenue for the twelve months ending March 31, 2026, was reported at $25.904 billion.
Amphenol designs, manufactures, and markets a wide array of high-technology interconnect, sensor, and antenna solutions. Their product offerings include fiber optic interconnects, harsh environment interconnects, high-speed interconnects, power interconnects, RF interconnect products, and various sensors (e.g., gas, moisture, pressure, temperature, position, vibration). Additionally, they provide coaxial, power, and specialty cables, as well as custom cable assemblies, rigid and flexible printed circuit boards, and combiner/splitter products. These products serve diverse end markets such as automotive, broadband communications, commercial aerospace, defense, industrial, information technology and data communications, mobile devices, and mobile networks.
Amphenol Corporation exhibits an active, two-way patent litigation posture, appearing as both a plaintiff and a defendant in tracked cases. The company has initiated two plaintiff cases, both at the Patent Trial and Appeal Board (PTAB). Conversely, Amphenol has defended against one case filed at the International Trade Commission (ITC). This distribution suggests that Amphenol actively asserts its intellectual property while also defending against infringement allegations from other entities.
The tracked cases indicate ongoing intellectual property disputes with Credo Technology Group Ltd. and Credo Semiconductor Inc. Specifically, Amphenol Corporation has filed two plaintiff cases against Credo Technology Group Ltd. at the PTAB, both in 2025. In a related matter, Credo Semiconductor Inc. and others filed a defendant case against Amphenol Corporation at the ITC in March 2025. These cases highlight a focused area of litigation activity concerning technology related to Credo and Amphenol's respective product spaces.
