Bourns Releases New Transient Current Suppressor (TCS)
High-Speed Protector Products
Riverside, California - TO BE RELEASED SEPTEMBER 7, 2012 - Bourns is pleased to announce the release
of new TCS™ High-Speed Protectors, designed to provide superior protection for very high data rate differen-
tial lines. Bourns® TCS-DL Series helps protect Gigabit Ethernet (GbE) and VDSL applications against faults
caused by short circuits, induction and lightning surges by limiting the maximum current to a safe level.
Bourns® TCS™ High-Speed Protectors are typically used in conjunction with low capacitance Transient
Voltage Suppressor (TVS) devices to form an extremely low let-through energy barrier to excessive voltages or
currents during surge events, which may damage high-speed, low voltage driver and receiver components.
The DL Series of Bourns® TCS™ High-Speed Protector products contain a dual, well-matched, low resistance,
bidirectional and very high-speed Transient Current Suppressor (TCS™) device.
