Bourns Inc.

Circuit protection is invisible until it fails—and that is exactly why Bourns earns a permanent seat on the BOM. From the Trimpot trimming potentiometer that launched the company in 1952 to today’s IsoMOV hybrid surge protectors and AEC-Q200 automotive inductors, Bourns covers the protection-power-sensing triangle. Their Multifuse PPTC resettable fuses protect USB ports; TBU high-speed blockers defend Ethernet PHYs from nanosecond transients; MOVs and GDTs absorb lightning surges on telecom lines. SiC Schottky diodes and trench-gate IGBTs are pulling Bourns deeper into EV power-converter designs. We source across the 3296, 3362, SRN, and CD series to keep production lines moving.
