Overview

Mouser Electronics is a global business-to-business distributor of electronic components and industrial automation products. The company supplies semiconductors, passive components, connectors, electromechanical products, embedded systems, development tools, and related technologies from a large portfolio of manufacturer brands. Its primary customers include electronics design engineers, procurement teams, contract manufacturers, educational institutions, and industrial users. Founded in El Cajon, California, in 1964 by Jerry Don Mouser, the company initially developed as a component distribution business and later built its identity around authorized distribution, broad product availability, and service for new and emerging technologies. Mouser moved its corporate headquarters to Mansfield, Texas, in 1986. The Texas site subsequently developed into a major corporate and logistics center serving the company’s international operations. Mouser became a wholly owned subsidiary of TTI, Inc. in January 2000. In December 2006, Berkshire Hathaway acquired majority ownership of TTI, bringing Mouser into the Berkshire Hathaway family of companies. Mouser remains a privately held operating subsidiary rather than a separately listed public company. The company’s digital commerce platform is central to its business model. Customers can search and order products from more than 1,200 manufacturer brands and access product specifications, datasheets, pricing, inventory information, technical documentation, and engineering tools. Its online services include bill-of-materials import and project-management functions, as well as calculators and tools intended to support component selection and product design. Mouser emphasizes rapid access to newly introduced products and technologies in addition to established component lines. Mouser’s global headquarters and distribution center occupy a large campus in the Dallas–Fort Worth region. The distribution operation maintains inventory covering more than one million unique stock-keeping units, according to company and reference descriptions, and has invested in warehouse automation, including a large installation of vertical lift modules. The company operates a network of international offices and customer-service or technical-support locations across the Americas, Europe, and Asia-Pacific. New offices in Lithuania and Australia expanded its geographic presence in 2023 and 2024. The brand’s market position is that of a broad-line, authorized component distributor focused on design engineers and buyers who need dependable sourcing, technical information, and access to current products. It competes with distributors such as DigiKey, Farnell, RS, and Master Electronics. In addition to commercial distribution, Mouser has participated in engineering education, technology content, industry associations, counterfeit-component avoidance initiatives, and supplier programs. Its awards and accreditations have included recognition from component manufacturers and the electronics distribution industry.

History

Mouser Electronics was founded in 1964 by Jerry Don Mouser in El Cajon, California. It developed as an authorized distributor serving the electronic-component market, with a focus on supplying parts and technical information to engineering and purchasing customers. In 1986, Mouser relocated its corporate headquarters to Mansfield, Texas, and expanded into a new facility. The move established the Dallas–Fort Worth area as the company’s long-term operational base. Over time, the Mansfield campus grew into a combined corporate and distribution operation supporting a large inventory and international fulfillment network. A major ownership transition occurred in January 2000, when Mouser became a wholly owned subsidiary of TTI, Inc., a Fort Worth-based distributor of electronic components. In December 2006, Berkshire Hathaway acquired majority ownership of TTI. Mouser consequently became part of Berkshire Hathaway’s group of operating companies while continuing to operate under its own brand and management structure. Mouser accelerated international development during the 2000s and 2010s. It opened an office in Shanghai in 2008 and subsequently developed customer-service and technical-support branches in numerous markets across the Americas, Europe, and Asia-Pacific. The company’s network has included locations in Brazil, Canada, Mexico, Hong Kong, mainland China, India, Japan, South Korea, Malaysia, the Philippines, Singapore, Taiwan, Thailand, Vietnam, Israel, Germany, the United Kingdom, France, Italy, the Netherlands, Spain, Sweden, Poland, and the Czech Republic. Further offices in Lithuania and Australia were reported in 2023 and 2024. The company’s business increasingly centered on digital commerce and engineering enablement. Its website combined searchable inventory with datasheets, pricing and availability information, conversion calculators, bill-of-materials import, and project-management features. The platform was designed not merely as a catalog but as a procurement and design-support resource for engineers and buyers. Mouser also expanded the range of manufacturer brands and new product introductions available through its channel. Logistics capacity became another important part of the company’s development. The Dallas–Fort Worth headquarters and distribution campus expanded in the early 2020s, with facilities described as covering approximately 1.5 million square feet and supporting inventory for more than one million unique products. Mouser invested in warehouse automation, including 216 vertical lift modules, described in the reference material as the largest such installation in North America. Mouser has also participated in industry efforts concerning supply-chain integrity. It co-sponsored the SAE Counterfeit Parts Avoidance Symposium in Canada in 2013 and received AC7403 accreditation from the Counterfeit Avoidance Accreditation Program in 2018. The accreditation was associated with demonstrating compliance with the AS6496 aerospace standard. The company has received recognition from industry associations and suppliers, including community-activism, customer-growth, new-product-growth, and eCatalog-distribution awards. In 2025, Jeff Newell was appointed president, with Glenn Smith continuing as chief executive officer. The reference material states that Smith was scheduled to retire at the end of 2026. Mouser’s continuing activities include authorized component distribution, online procurement, engineering content, inventory management, international fulfillment, and support for industrial automation and electronics design markets.
