BournsTBU® 高速保护器

The TBU® high-speed protector placed in the system circuit will monitor the current with the MOSFET detection circuit triggering, to provide an effective barrier behind which sensitive electronics will not be exposed to large voltages or currents during surge events at the high speed I/O port such as CAN bus, RS485 and RS232 etc, which is used for Communications – Industrial IoT & Edge Computing. Also, a TBU has excellent High Frequency Characteristics to protect the over current and over voltage issues without causing the S.I. issues.

Bourns TBU® 高速保护器 (HSP) 为电流抑制器 (ECL)，可为雷电、电源感应、电源交叉、接地电位升高 (EPR) 或其他能量浪涌条件提供浪涌保护。通常用于VoIP、以太网络、RS-485、RS-232、CANbus、LVDS、同轴等接口，协助通过GR-1089、K.20/45/21标准。

Bourns TBU® 电路保护器件可用于 RS-485 通信介面应用和 AISG（天线介面标准小组）数据机保护。透过电流断开机制在纳秒内阻止瞬变，而不是将浪涌转移或分流到地。这些高速浪涌保护组件旨在防止因短路、交流电源交叉、感应和雷击浪涌引起的故障。 Bourns TBU 电路保护器件可在多次故障事件后复位以实现全部功能，是电信、工业和数据通信系统的理想选择。
