The AT-cut provides excellent frequency stability over temperature with an inflection point near 25C. When placed in the feedback path of an oscillator circuit with appropriate load capacitance, the piezoelectric effect sustains precise oscillation. The metal can HC-49\/SMD package provides hermetic sealing and good thermal stability.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Crystal<\/td><td>One terminal of quartz resonator<\/td><\/tr><tr><td>2<\/td><td>Crystal<\/td><td>Other terminal of quartz resonator<\/td><\/tr><\/table>","application_scenarios":"<ul><li>USB clock generation<\/li><li>Microcontroller oscillator<\/li><li>Wireless module reference clock<\/li><li>Industrial timing applications<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>ABM8-24.000MHZ-20-B2X-T<\/td><td>Abracon<\/td><td>24MHz 3225<\/td><td>3.2x2.5mm<\/td><\/tr><tr><td>ECS-240-20-3X-TR<\/td><td>ECS<\/td><td>24MHz HC49S<\/td><td>11.4x4.8mm<\/td><\/tr><tr><td>FX135A-240 24MHz<\/td><td>Ikeji<\/td><td>24MHz HC49S<\/td><td>11.4x4.8mm<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/9837","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/comments?post=9837"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/9837\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/media?parent=9837"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/categories?post=9837"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/tags?post=9837"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=9837"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
