Part of Vishay's industry-leading WSL series, this metal element resistor uses a solid metal alloy resistive element that provides an ultra-low \u00b175ppm\/\u00b0C temperature coefficient and excellent long-term stability. The AEC-Q200 qualification, combined with anti-sulfur, moisture-resistant, and pulse-withstanding features, makes it suitable for demanding automotive and industrial applications. The 4-terminal (Kelvin) pad layout enables precise voltage measurement by separating the current path from the sense connections.","working_principle":"The WSL2512R0500FEA uses Vishay's proprietary Power Metal Strip construction, where a solid metal alloy resistive element is welded to copper terminals. Unlike thick film or thin film resistors, the metal alloy element provides an inherently low and stable temperature coefficient (\u00b175ppm\/\u00b0C) because the alloy composition is precisely controlled during manufacturing. The 4-terminal (Kelvin) pad layout on the PCB separates the high-current path (through the outer pads) from the voltage sensing connections (inner pads), eliminating the measurement error caused by solder joint and PCB trace resistance. The all-welded construction provides excellent pulse withstanding capability, as the metal element can absorb transient energy without degradation.","pin_description":"<table>\n<tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>1<\/td><td>I+ (Current In)<\/td><td>Power<\/td><td>High-current input terminal<\/td><\/tr>\n<tr><td>2<\/td><td>S+ (Sense +)<\/td><td>Sense<\/td><td>Voltage sense positive (Kelvin connection)<\/td><\/tr>\n<tr><td>3<\/td><td>I- (Current Out)<\/td><td>Power<\/td><td>High-current output terminal<\/td><\/tr>\n<tr><td>4<\/td><td>S- (Sense -)<\/td><td>Sense<\/td><td>Voltage sense negative (Kelvin connection)<\/td><\/tr>\n<\/table>","application_scenarios":"<ul>\n<li>Automotive BMS 48V mild-hybrid battery pack current sensing up to 20A continuous<\/li>\n<li>USB PD 65W\/100W charger output current monitoring and OCP<\/li>\n<li>Server blade 12V rail current monitoring with digital power manager<\/li>\n<li>DC-DC converter current mode control feedback with 50mV\/A sense voltage<\/li>\n<li>Motor drive inverter DC-link current sensing for overcurrent protection<\/li>\n<\/ul>","alternative_models":"<table>\n<tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr>\n<tr><td>Vishay<\/td><td>WSL2512R0500FEB<\/td><td>2512<\/td><td>50m\u03a9 1% alternative packaging<\/td><\/tr>\n<tr><td>Bourns<\/td><td>CRA2512-FZ-R050ELF<\/td><td>2512<\/td><td>50m\u03a9 1% metal element<\/td><\/tr>\n<tr><td>YAGEO<\/td><td>RL2512FK-0R050L<\/td><td>2512<\/td><td>50m\u03a9 1% metal strip<\/td><\/tr>\n<tr><td>Panasonic<\/td><td>ERJMS1SF50mU<\/td><td>2512<\/td><td>50m\u03a9 1% metal plate<\/td><\/tr>\n<tr><td>Samsung<\/td><td>CS25GTFR050<\/td><td>2512<\/td><td>50m\u03a9 1% current sense<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/10981","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=10981"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/10981\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media?parent=10981"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/categories?post=10981"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/tags?post=10981"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/chip_brand?post=10981"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
