Pending) high performance, low cost and compact solutions for TO-220, TO-247 and TO-264 , or similar packages. This powerful heat sink provides tool and fixture free assembly operation, largest surface areas and smallest space occupation. It is the ideal type of heat sink for high power density and small size (1U or 2U) electronic packaging with forced convention cooling. Features & Benefits Minimum assembly cost and labor Spring Clips make the mounting holes, fasteners, tools and fixtures obsolete in assembly operations & reduce costs. Maximum Repeatability Constant spring force over repeated assembly/disassembly Maximum Reliability Resilient spring action locks electronic component in place. Fewer parts in assembly and no fasteners and washers required. Prevent short circuit by eliminating metal particles generated from hardware or thread tapping Design Flexibility Maximum flexibility for dynamic device locations and power up grading. Configure-to-Fit gives designers total freedom to configure heat sink needed to fit their dynamic design environments. Specifications Heat Sink: Aluminum Alloy 6063-T5 or Equivalent with black anodized finish. Spring Clip: Music Wire, Per ASTM A228 with bright nickel plating Solder Foot: Cold-rolled Steel, Per ASTM A-366 with pure tin over copper strike. RoHS compliant.
