Bourns, Inc. is an American electronics company that develops, manufactures and supplies electronic components for a variety of industries including automotive, industrial, instrumentation, medical electronics, consumer equipment and portable electronics. [1]
Established in Altadena, California in 1947 by Marlan and Rosemary Bourns, graduates of the University of Michigan, the company was founded to develop and sell electronic components and sensors to the aerospace industry. [2]
Bourns has 15 manufacturing facilities around the world and has continued growing through the development of new products and technologies as well as through acquisitions. The company has approximately 9000 employees worldwide. [3]
Its current Chairman of the Board and CEO is Gordon Bourns, [4] the son of the co-founders. [5]
Marlan and Rosemary Bourns started the company in their 384-square-foot (35.7 m2) garage in Altadena, California in 1947. Their invention of linear motion and vane position potentiometers provided a method of accurately determining an aircraft's pitch, and helped to grow their business into a global corporation.
Headquartered in Riverside, California, Bourns makes and provides a broad range of electronic components and circuit protection devices including automotive sensors, circuit protection solutions, magnetic and inductor products, specialty engineering and manufacturing services, precision potentiometers, panel controls, encoders and resistive products.
In 1952, Bourns patented the trimming potentiometer, trademarked "Trimpot". [6] [7] In 1995, Bourns acquired VRN's Trimmer assets and introduced the first 4 mm surface-mount sealed tact switch. In 2008, Bourns acquired the Transient Blocking Unit (TBU) assets of Fultec Semiconductor, Inc. [8]
An integrated circuit, also known as a microchip, chip or IC, is a small electronic device made up of multiple interconnected electronic components such as transistors, resistors, and capacitors. These components are etched onto a small piece of semiconductor material, usually silicon. Integrated circuits are used in a wide range of electronic devices, including computers, smartphones, and televisions, to perform various functions such as processing and storing information. They have greatly impacted the field of electronics by enabling device miniaturization and enhanced functionality.

An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components and elements. A datasheet for an electronic component is a technical document that provides detailed information about the component's specifications, characteristics, and performance.

A trimmer, or preset, is a miniature adjustable electrical component. It is meant to be set correctly when installed in some device, and never seen or adjusted by the device's user. Trimmers can be variable resistors (potentiometers), variable capacitors, or trimmable inductors. They are common in precision circuitry like A/V components, and may need to be adjusted when the equipment is serviced. Trimpots are often used to initially calibrate equipment after manufacturing. Unlike many other variable controls, trimmers are mounted directly on circuit boards, turned with a small screwdriver and rated for many fewer adjustments over their lifetime. Trimmers like trimmable inductors and trimmable capacitors are usually found in superhet radio and television receivers, in the intermediate frequency (IF), oscillator and radio frequency (RF) circuits. They are adjusted into the right position during the alignment procedure of the receiver.

Thick-film technology is used to produce electronic devices/modules such as surface mount devices modules, hybrid integrated circuits, heating elements, integrated passive devices and sensors. Main manufacturing technique is screen printing (stenciling), which in addition to use in manufacturing electronic devices can also be used for various graphic reproduction targets. It became one of the key manufacturing/miniaturisation techniques of electronic devices/modules during 1950s. Typical film thickness – manufactured with thick film manufacturing processes for electronic devices – is 0.0001 to 0.1 mm.

Embedded intelligence is characterized as the ability of a product, process, or service to reflect on its own operational performance, usage load, or environment. The motivation for this may be to enhance the performance, lifetime, or quality of the product. This self-reflection might be facilitated by information collected via embedded sensors, and processed locally or communicated remotely for processing.
