Vishay Expands Resistor Portfolio Through Ametherm Acquisition

Vishay Intertechnology, Inc., one of the world’s largest manufacturers of discrete semiconductors and passive electronic components, announced that it has acquired Ametherm, Inc., a leader in inrush current limiters and sensing thermistors, for approximately $31.5 million in cash.

Ametherm specializes in precision thermistors for inrush current limiters and temperature sensing that come in various sizes, forms and packages to meet the demands of the automotive, industrial, aerospace/defense and medical markets. The company offers the highest-rated NTC thermistors and PTC thermistors in customizable versions to meet the needs of specific applications for circuit protection.

“Acquiring Ametherm is an illustration of two of the eight strategic levers Vishay is employing to accelerate growth. We are expanding our product portfolio and filling technology gaps through M&A and enhancing innovation to support deeper technical engagement with our customers. Ametherm brings Vishay small package sizes, high voltages, and high-quality PTC inrush current limiters and NTC temperature sensors required in all high energy applications,” said Joel Smejkal, President and CEO of Vishay.

“Ametherm has products that can support the current market needs (ex. 800VDC for EVs) and the future needs up to 2000VDC in pre-charge circuits. Our distribution customers have indicated that Ametherm’s technology piques the interest of design engineers. Our sales, marketing and business development will increase the global promotion of Ametherm products and our regionalized manufacturing footprint will bring Ametherm operational advantages.”

“Innovation, whether organic or acquired, has always been important to Vishay,” said Marc Zandman, Executive Chairman of the Board. “The Board supports management’s continued investments to more broadly serve our addressable market and to expand our product and technology portfolio.”
