PGB1040805MR Datasheet | Littelfuse

Overview Pulse Guard ESD Suppressors help protect sensitive electronic equipment against electrostatic discharge (ESD). They supplement the on-chip protection of integrated circuitry and are best suited for lowvoltage, high-speed applications where low capacitance is important. Data ports utilizing such high-speed protocols as USB 2.0, IEEE1394, HDMI and DVI can benefit from this new technology. Pulse Guard suppressors use polymer posite materials to suppress fast-rising ESD transients (as specified in IEC 61000-4-2 and MIL-STD-883E), while adding virtually no capacitance to the circuit. Features - Lead-Free - Ultra-low capacitance - Low leakage current - Fast response time - 4-lines of protection - Bi-directional - Withstands multiple ESD strikes - Based on industry standard 2012 package - patible with pick-and-place processes - Available in 1,000 and 5,000 piece reels (EIA-RS481) Reference Dimensions: Reflow Solder 0.71 (.028") 1.27 (.050") 2.03 (.080") TYP Typical Applications - - - - - - HDTV Hardware Laptop/Desktop puters Network Hardware puter Peripherals Digital Cameras External Storage 0.635 (.025") 0.74 (.029") 1.27 (.050") TYP 0.51 (.020") 0.279 (.011") Sn 0.203 (.008") TYP 0.127 (.005") TYP 0.74 (.029") - Set-Top Boxes NOTE: When wave soldering, the gap between pads should be covered with photo-imageable solder mask to prevent bridging between terminations under the ponent. Also the spacing between the ground contacts should be increased from .635mm (.025") to .889 (.035"). 0.406 (.016") TYP Ordering Information CATALOG NUMBER PGB1040805MR PGB1040805NR PIECES PER REEL 1,000 5,000 2 5 Equivalent Circuit 1 6 Design Consideration Because of the fast rise-time of the ESD transient, placement of Pulse Guard suppressors is a key design consideration. To achieve optimal ESD suppression, the devices should be placed on the circuit board as close to the source of the ESD transient as possible. Install Pulse Guard suppressors directly behind the connector...
