Bourns TBU-RS055-300-WH Dual-Channel High-Speed Protector

Bourns TBU-RS055-300-WH Dual-Channel Bidirectional Protectors are TBU-RS high-speed devices used in RS-485 communication interfaces. Bourns TBU-RS055-300-WH includes a 550V maximum impulse voltage and 250V maximum RMS voltage. This transient blocking unit overcurrent and TVS overvoltage protector is an integrated solution that aids compliance with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards. TBU-RS055-300-WH takes up less than half the board space of a discrete solution.
