The SM4 designation indicates a 4-pad SMT footprint design that provides enhanced mechanical stability on the PCB compared to standard 2-pad designs. The PH series is one of the most popular wire-to-board connector systems in the electronics industry, offering a reliable and cost-effective solution for internal wiring. The 2A current rating per contact and 100V voltage rating make it suitable for both signal and low-power applications. The side-entry (right-angle) orientation allows cable routing parallel to the PCB surface, which is essential for low-profile enclosures. The fully shrouded header design protects contacts from damage and ensures correct mating orientation.","working_principle":"The B3B-PH-SM4-TBT(LF)(SN) operates as part of a disconnectable crimp-style connector system. The header is soldered to the PCB using reflow soldering, with the SM4 4-pad design providing additional solder joints for mechanical strength against vibration and cable pull forces. The mating wire housing (PHR-3) accepts SPH-002T-P0.5S or SPH-002T-P0.5L crimp contacts, which are crimped onto 30-24 AWG wires using appropriate tooling. The phosphor bronze contacts with tin plating (reflow-treated) provide reliable electrical connection with initial contact resistance of 10m\u03a9 max. The 2.0mm pitch allows for compact PCB layouts while maintaining adequate creepage and clearance distances for the 100V rating. The withstanding voltage of 800V AC\/minute ensures reliable insulation between adjacent circuits.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Circuit 1<\/td><td>Signal\/Power<\/td><td>First contact position (marked on housing)<\/td><\/tr><tr><td>2<\/td><td>Circuit 2<\/td><td>Signal\/Power<\/td><td>Second contact position<\/td><\/tr><tr><td>3<\/td><td>Circuit 3<\/td><td>Signal\/Power<\/td><td>Third contact position<\/td><\/tr><\/table>","application_scenarios":"<ul><li><strong>Consumer Electronics:<\/strong> Internal power and signal wiring for laptops, cameras, and audio equipment with 2A per circuit sufficient for most sub-system power rails.<\/li><li><strong>White Goods:<\/strong> Control board connections in washing machines, refrigerators, and microwave ovens where the side-entry orientation fits within slim enclosures.<\/li><li><strong>Industrial Control:<\/strong> Sensor and actuator signal interfaces in PLCs and motor controllers with reliable PH series mating.<\/li><li><strong>Battery Systems:<\/strong> Cell balancing and BMS signal connections with 100V rating providing adequate margin for multi-cell packs.<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Pitch<\/th><th>Circuits<\/th><th>Notes<\/th><\/tr><tr><td>JST<\/td><td>S3B-PH-K-S(LF)(SN)<\/td><td>2.0mm<\/td><td>3<\/td><td>Through-hole top-entry variant<\/td><\/tr><tr><td>JST<\/td><td>B4B-PH-SM4-TBT(LF)(SN)<\/td><td>2.0mm<\/td><td>4<\/td><td>4-circuit version<\/td><\/tr><tr><td>Molex<\/td><td>53047-0310<\/td><td>2.0mm<\/td><td>3<\/td><td>KK-compatible alternative<\/td><\/tr><tr><td>Hirose<\/td><td>DF11-3DP-2DS(24)<\/td><td>2.0mm<\/td><td>3<\/td><td>2mm pitch alternative<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/10267","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=10267"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/10267\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/media?parent=10267"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/categories?post=10267"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/tags?post=10267"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=10267"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
