Packaged in the 0805 (2012 metric) footprint, it delivers 0.25W power rating with a maximum working voltage of 150V. The anti-sulfuration construction uses a high sulfuration-proof inner top electrode material, ensuring reliable operation in sulfur-containing atmospheres. AEC-Q200 qualified, this resistor provides excellent long-term stability with \u0394R of \u00b10.2% in reliability testing.","working_principle":"The RS73 series uses a metal-glaze thick film resistor element on a ceramic substrate with precision laser trimming for ultra-tight tolerance control. The anti-sulfuration construction features a special inner top electrode material that resists silver migration and sulfide formation. The RuO2-based thick film provides excellent stability under thermal cycling, humidity, and load life testing. The \u00b125 ppm\/\u00b0C TCR is achieved through careful material selection and process control, making this series suitable for precision measurement applications.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Terminal 1<\/td><td>Passive<\/td><td>Resistor connection (Sn-plated)<\/td><\/tr><tr><td>2<\/td><td>Terminal 2<\/td><td>Passive<\/td><td>Resistor connection (Sn-plated)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Precision measurement bridge circuits<\/li><li>Automotive sensor calibration and signal conditioning<\/li><li>Medical instrumentation precision dividers<\/li><li>Industrial process control feedback networks<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Panasonic<\/td><td>ERA-6AEB751V<\/td><td>0805<\/td><td>750\u03a9, 0.1%, 25ppm<\/td><\/tr><tr><td>Vishay<\/td><td>TNPW08057500BEEN<\/td><td>0805<\/td><td>750\u03a9, 0.1%<\/td><\/tr><tr><td>Yageo<\/td><td>RT0805BRE-07750RL<\/td><td>0805<\/td><td>750\u03a9, 0.1%<\/td><\/tr><tr><td>KOA<\/td><td>RS73F2ATTD7501B<\/td><td>0805<\/td><td>7.5k\u03a9, 0.1%<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/10328","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=10328"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/10328\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=10328"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=10328"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=10328"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=10328"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
