Mouser Electronics Brand Guidelines: A Teacher’s 1964 Parts Shop, TTI & Berkshire Hathaway

A physics teacher selling parts to his students.

Mouser Electronics started in a classroom. Electronic Design, marking the company’s 60th anniversary on 28 February 2024, reported that in 1964 Jerry Mouser, a high-school physics teacher, began selling electronic equipment and parts to students in El Cajon, California, east of San Diego. The business was then called Western Components. English Wikipedia gives the same founder, town and year.

The family name arrived later. According to the same Electronic Design article, Western Components formally changed its name to Mouser Electronics in 1973, and Glenn Smith joined the twelve-person company as a part-time warehouse worker, the start of a career that took him to the top of the business.

The move to Texas came in two steps. Electronic Design says Mouser opened a warehouse in Mansfield, Texas, in 1983, close to the Dallas/Fort Worth airport, and moved its corporate headquarters there three years later; English Wikipedia dates the headquarters move to 1986. Mansfield, on the southern edge of the Dallas–Fort Worth area, has been the company’s base ever since, and English Wikipedia describes a campus of about 100 acres that holds both the global headquarters and the main distribution centre. At its 60th anniversary Electronic Design put the company at about 4,000 employees across 28 facilities worldwide.

A new print catalogue every 90 days.

For decades Mouser’s public face was its printed catalogue. In February 2008 Electronic Specifier reported the release of Catalog 633, quoting the company’s then president and chief executive, Glenn Smith, on its practice of publishing a new print catalogue every 90 days while updating its online catalogue daily; the release described Mouser as the only major distributor doing so, which is the company’s own claim.

The same 2008 report gives a description of the catalogue’s design. New products, new technologies and new suppliers were flagged with coloured logos and banners, and four-colour section guides on heavy stock marked the product categories, so a reader could find a family of parts by its tab. The catalogue was mailed quarterly to a worldwide list and worked alongside the website, which already carried hundreds of thousands of products and downloadable data sheets.

That emphasis on new product introduction runs through Mouser’s self-description. In the 2008 release Smith said the aim was to let engineering customers integrate the newest technology into designs quickly. English Wikipedia describes today’s site as listing products from about 1,200 manufacturer brands, with tools such as a bill-of-materials import for project management.

The warehouse grew with the range. A December 2006 announcement noted that Mouser had recently completed a major facility expansion, and English Wikipedia says a further expansion of the Texas headquarters and distribution centre was completed in early 2020, and that the site uses 216 vertical lift modules for automated storage. International offices followed from 2008, beginning with Shanghai, according to the same article.

English Wikipedia also records industry recognition, including an award from the Electronic Components Industry Association in 2013 and being named Molex’s eCatalog Distributor of the Year in 2020, and says Mouser in 2018 became the first component distributor accredited to the AC7403 counterfeit-avoidance standard.

How distributors present themselves.

Electronic-component distributors sit between the companies that make chips, passives and connectors and the engineers who design them into products. For much of the twentieth century their public face was paper: thick printed catalogues, reissued at intervals and kept on the shelf beside the workbench, listing thousands of parts by type, value and package. Many of these businesses began as shops selling radio parts over the counter, and the catalogue carried that counter into offices and factories.

Today the catalogue has largely given way to the search box. Distributor websites lead with a part-number search, filters for specifications and stock levels, and datasheets a click away; the printed book survives, where it survives at all, as a reference rather than the main way to order. Photographs in these companies’ own material tend to show the warehouse behind the website: long aisles of reels, trays and anti-static bins, picking stations and parcels on conveyors, often paired with promises of same-day shipping on orders placed before a cut-off time.

The audience has widened too. Alongside franchised lines from chip makers, distributors now sell development boards, evaluation kits and maker-friendly modules to students, hobbyists and start-ups as well as to large manufacturers, and many run online communities and training material for engineers. Franchised distributors and catalogue houses present themselves differently: the first stress their relationships with manufacturers and their design support, the second their range and speed.

Much of the trade still meets in person. Engineers and buyers walk the stands at shows such as electronica in Munich, Embedded World in Nuremberg and CES in Las Vegas, where distributors take booths beside the manufacturers whose parts they sell. This guide sets out what can be checked about each company — who founded it, who owns it now and how it has changed — and marks clearly what rests only on the company’s own word.

A subsidiary of a subsidiary of Berkshire Hathaway.

Mouser has not been independent since 2000. English Wikipedia says that in January 2000 the company became a wholly owned subsidiary of TTI, Inc., the Fort Worth distributor of passive components and connectors founded by Paul Andrews in 1971. Electronic Design says Glenn Smith became president and chief executive of Mouser four years later.

The next owner arrived through TTI. On 22 December 2006 TTI and Berkshire Hathaway announced a definitive agreement under which Berkshire would buy TTI, including its subsidiary Mouser Electronics, according to the release published on Berkshire Hathaway’s website; the terms were not disclosed, and TTI was to operate as a wholly owned subsidiary with its management in place. The release said the deal was expected to close in the first quarter of 2007, and English Wikipedia’s article on TTI says it was completed on 30 March 2007. In that announcement Warren Buffett called Andrews “a remarkable man who has built an outstanding business,” and Andrews said it was an honour for TTI and Mouser to join the group.

Inside that structure Mouser kept its own name and its own market. Berkshire’s 2006 release described TTI as a specialist distributor of passive, interconnect and electromechanical components for manufacturers, while English Wikipedia’s TTI article calls Mouser a broad-line catalogue distributor focused on new products for design engineers and buyers. English Wikipedia lists offices across the Americas, Europe and Asia, with Lithuania and Australia added in 2023 and 2024, and says Jeff Newell was appointed president in 2025, with Glenn Smith continuing as chief executive.

For a design guide, Mouser Electronics shows how a catalogue’s working tools — coloured flags, tabbed sections, a steady publishing rhythm — can carry a brand for decades. Compare TTI, the parent company in Fort Worth, and DigiKey, another American catalogue house that began with hobbyists. For this guide we use a deep navy, steel grey and amber with a sans, an unofficial interpretation; no product or logo is reproduced.
