Packaged in the 0805 (2012 metric) footprint with 0.25W power rating and 150V maximum working voltage. The anti-sulfuration design ensures reliable performance in harsh automotive and industrial environments. AEC-Q200 qualified with excellent long-term stability of \u0394R \u00b10.2% in reliability testing.","working_principle":"The RS73 series uses a RuO2-based metal-glaze thick film resistor element on a ceramic substrate with precision laser trimming for ultra-tight tolerance. The anti-sulfuration construction features a special inner top electrode material resistant to silver sulfide formation. This design maintains stable resistance under harsh conditions including sulfur exposure, thermal cycling, and humidity. The tight TCR of \u00b125 ppm\/\u00b0C ensures minimal resistance drift over the full operating temperature range.","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>Current sensing in precision power management<\/li><li>Automotive sensor bridge circuits<\/li><li>Operational amplifier gain-setting networks<\/li><li>Industrial calibration and reference circuits<\/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-6AEB121V<\/td><td>0805<\/td><td>120\u03a9, 0.1%, 25ppm<\/td><\/tr><tr><td>Vishay<\/td><td>TNPW08051200BEEN<\/td><td>0805<\/td><td>120\u03a9, 0.1%<\/td><\/tr><tr><td>Yageo<\/td><td>RT0805BRE-07120RL<\/td><td>0805<\/td><td>120\u03a9, 0.1%<\/td><\/tr><tr><td>KOA<\/td><td>RS73F2ATTD1201B<\/td><td>0805<\/td><td>1.2k\u03a9, 0.1%<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/10329","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/comments?post=10329"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/10329\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media?parent=10329"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/categories?post=10329"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/tags?post=10329"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/chip_brand?post=10329"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
