GDT operates and will survive with Fail-Short activation. - At delivery AQL 0.65 Level II, DIN ISO 2859. - Models with the optional Fail-Short assembly activate at low temperature (215 °C – 217 °C) when required. These models are designed to be soldered either manually or using a selective soldering process that does not exceed 210 °C, below the temperature that the Fail-Short assembly would activate. ~~**Applications**~~ **Port Protection GDT Device P/N TBU[®] Device P/N** CanBus 2020-23T TBU-CA065-100-WH RS232 2020-23T TBU-CA065-200-WH RS422 2020-23T TBU-CA065-200-WH RS485 2020-23T TBU-CA065-200-WH RS485 2020-42T TBU-CA085-200-WH SDI 2020-23T TBU-CA065-100-WH VDSL 2020-15T TBU-CA050-500-WH “TBU” is a registered trademark of Bourns, Inc. in the United States and other countries. ~~=>~~ *RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011. ~~>~~ Specifications are subject to change without notice.
