The C650 & C850 Series are currently Features available, but not recommended for Formerly brand new designs. Bourns TBU-CA Extremely high speed performance Series is preferred. Blocks high voltages and currents Very high bandwidth GHz compatible Small package, minimal PCB area Simple, superior circuit protection RoHS compliant*, UL Recognized C650 and C850 Series TBU High-Speed Protectors Transient Blocking Units - TBU Devices Agency Approval Bourns C650 and C850 series products are high-speed UL recognized component File E315805. bidirectional protection components, constructed using MOSFET semiconductor technology, designed to protect Industry Standards against faults caused by short circuits, AC power cross, induction and lightning surges. Description Model The TBU high-speed protector, triggering as a function of C650 the MOSFET, blocks surges and provides an effective barrier GR-1089 Port Type 1, 3, 5 C850 behind which sensitive electronics are not exposed to large Telcordia voltages or currents during surge events. The TBU device is C650 GR-974 provided in a surface mount DFN package and meets industry C850 standard requirements such as RoHS and Pb Free solder ITU-T K.20, K.20E, K.21, K.21E, K.45 C850 re ow pro les.
