Gemini Kelvin is an ideal solution for devices such as power controllers, A-D and D-A converters, power amplifiers and audio and video circuits.<\/p>\n<p>At 3.22 mm test height, the Gemini Kelvin is an excellent all-around spring probe with low inductance, high bandwidth, and excellent current-carrying capacity. The DUT side tip design accurately maintains its 100 \u00b5m spacing for the life of the probe. Customers report typical probe life of 500 k to 800 k package insertions, or over 2M touchdowns at wafer-level test. The offset tip allows manageable board layout with a board-side spacing of 0.4 mm.<\/p>\n<div  class='avia-button-wrap av-18a7y4-308ee268d1c35757d79153495d048738-wrap avia-button-left  avia-builder-el-16  el_after_av_button  el_before_av_button '><a href='https:\/\/www.cohu.com\/geminikelvin'  class='avia-button av-18a7y4-308ee268d1c35757d79153495d048738 av-link-btn avia-icon_select-no avia-size-medium avia-position-left avia-color-dark'   aria-label=\"Read More\"><span class='avia_iconbox_title' >Read More<\/span><\/a><\/div>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-5hijq8-a0ea8b4e4114dcbde77f5b4bb960ac6b'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-7' data-fake-id='#toggle-id-7' class='toggler  av-title-above av-inherit-font-color hasCustomColor av-inherit-border-color'  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-7' data-slide-speed=\"200\" data-title=\"ICON Coaxial Contactor\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: ICON Coaxial Contactor\" data-aria_expanded=\"Click to collapse: ICON Coaxial Contactor\">ICON Coaxial Contactor<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-7' aria-labelledby='toggle-toggle-id-7' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color av-inherit-font-color hasCustomColor av-inherit-border-color'  itemprop=\"text\" ><p><span style=\"color: #0053a1;\"><strong>Coaxial production solution for testing high end digital applications to 60 Gbps<\/strong><\/span><\/p>\n<p>Designed specifically for maintaining the native impedance of the device-under-test (DUT) through the contactor to the test system, maximizing high frequency power transfer by minimizing signal reflections (Return Loss).<\/p>\n<p>The ICON\u2019s metal body is a Faraday shield\/cage, which reduces cross talk (electromagnetic radiation) the primary cause of signal jitter.
