Bourns, Inc. is a globally recognized manufacturer of high-reliability electronic components, headquartered in Riverside, California. Renowned for its engineering excellence, the company delivers critical solutions across a diverse range of demanding markets, including automotive, industrial, consumer electronics, telecommunications, and medical equipment. The Bourns product portfolio is anchored by an industry-leading selection of passive components and circuit protection devices. The brand is particularly dominant in magnetic components, offering thousands of high-performance power inductors, alongside specialized RF and toroidal inductors engineered for optimized power management and signal integrity. Equally prominent is their comprehensive suite of circuit protection solutions. This robust lineup features a vast array of standard and resettable fuses, transient voltage suppressors (including TVS varistors and diodes), and gas discharge tubes (GDTs) designed to rigorously safeguard sensitive electronics against overvoltage and overcurrent faults. Beyond its core passives and protection technologies, Bourns manufactures highly effective EMC and RFI suppression components, such as common mode chokes and power line filters. The company's offering also extends into discrete semiconductors and power management, including Schottky diodes, fast recovery rectifiers, bridge rectifiers, and board-level transformers. This expansive breadth of quality components provides design engineers with a trusted foundation for developing resilient, efficient, and long-lasting electronic systems.
About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
