With \u00b15% tolerance and 0.063W power rating, this low-value resistor is suitable for current limiting, signal damping, and low-resistance bias applications. The 0402 footprint enables compact PCB layouts while the thick film technology provides cost-effective performance for general-purpose applications. The Ni barrier Sn-plated termination ensures reliable solder joints in lead-free reflow processes.","working_principle":"The FCF03FT-01B uses a thick film resistive element composed of a metal glaze (ruthenium oxide based) deposited on a high-purity alumina ceramic substrate. The resistive layer is laser-trimmed to achieve the target 1\u03a9 resistance with \u00b15% tolerance. The three-layer electrode structure (silver inner, nickel barrier, tin outer) provides reliable solderability and prevents silver migration. The low 1\u03a9 resistance makes this device suitable for current sensing applications where a small voltage drop proportional to load current is developed across the resistor.","pin_description":"<table>\n<tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>1<\/td><td>Terminal 1<\/td><td>Passive<\/td><td>One end of resistive element<\/td><\/tr>\n<tr><td>2<\/td><td>Terminal 2<\/td><td>Passive<\/td><td>Other end of resistive element<\/td><\/tr>\n<\/table>","application_scenarios":"<ul>\n<li>DC-DC converter output inductor damping resistor in parallel with output capacitor<\/li>\n<li>Multi-LED string current sharing ballast resistor<\/li>\n<li>Low-side current sense amplifier feedback element<\/li>\n<li>Speaker crossover network low-value resistor<\/li>\n<li>Motor driver gate resistor for switching noise damping<\/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>YAGEO<\/td><td>RC0402JR-071RL<\/td><td>0402<\/td><td>1\u03a9 5%, RC series<\/td><\/tr>\n<tr><td>Panasonic<\/td><td>ERJ2GEJ1R0X<\/td><td>0402<\/td><td>1\u03a9 5%<\/td><\/tr>\n<tr><td>Vishay<\/td><td>CRCW04021R00JNED<\/td><td>0402<\/td><td>1\u03a9 5% AEC-Q200<\/td><\/tr>\n<tr><td>Samsung<\/td><td>RC1005J1R0CS<\/td><td>0402<\/td><td>1\u03a9 5%<\/td><\/tr>\n<tr><td>Bourns<\/td><td>CR0402-1R0JW<\/td><td>0402<\/td><td>1\u03a9 5%<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/10970","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/comments?post=10970"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/10970\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/media?parent=10970"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/categories?post=10970"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/tags?post=10970"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=10970"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
