KEY:
217 SERIES
Compatible with surface mount technology (SMT) automated production techniques for ease of assembly and a
variety of soldering methods, these heat sinks allow greater packaging densities and reduction in PC-board area,
increasing the power dissipation of surface mount devices (SMDs) while maintaining and improving manufacturers'
component thermal specifications.
FEATURES AND BENEFITS:
• No interface material is needed
• Copper with tin-lead plating for improved solderability and assembly
• Both the component and the heat sink are installed on the PC-board utilizing
• EIA standards and ESD protection are specified
• Can be used with water soluble or no clean SMT solder creams or other pastes
