The UL94 V-0 nylon housing won't sustain a flame in an enclosed equipment panel — a standard requirement for anything inside a UL-listed enclosure. The base product number is SM03B-ZE; the suffix TB(LF)(SN) indicates Tape & Reel packaging with lead-free solder. Cut Tape quantities are also available through the same package options.","metaTitle":"SM03B-ZESS-TB(LF)(SN) JST ZE Header 3-Pin 1.5mm SMT Right","metaDescription":"JST ZE series 3-position header, 1.50mm pitch, 2A, 100V, SMT right-angle, tin-plated, locking ramp, shrouded 4-wall, UL94 V-0.","metaKeywords":null},"attributes":{"series":"ZE","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"JST Sales America Inc.","Style":"Board to Cable/Wire","Series":"ZE","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Solder Retention","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Outer Shroud Contact","Contact Shape":"Rectangular","Mounting Type":"Surface Mount, Right Angle","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"1","Pitch - Mating":"0.059\\\" (1.50mm)","Product Status":"Active","Voltage Rating":"100V","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.228\\\" (5.80mm)","Ingress Protection":"-","Base Product Number":"SM03B-ZE","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"2A","Operating Temperature":"-25°C~85°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.60000","currency":"USD"},{"qty":10,"price":"$0.52600","currency":"USD"},{"qty":100,"price":"$0.43370","currency":"USD"},{"qty":500,"price":"$0.37710","currency":"USD"},{"qty":1000,"price":"$0.31111","currency":"USD"},{"qty":2000,"price":"$0.30168","currency":"USD"},{"qty":3000,"price":"$0.28282","currency":"USD"},{"qty":5000,"price":"$0.27340","currency":"USD"},{"qty":10000,"price":"$0.25454","currency":"USD"},{"qty":25000,"price":"$0.24511","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f14c5b3e962d599e7da113c02f467e6a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SM03B-ZESS-TB(LF)(SN) RoHS compliant?","answer":"Yes, it carries ROHS3 compliance — the (LF)(SN) suffix in the part number indicates lead-free and tin-terminated finish."},{"question":"What is the pinout of SM03B-ZESS-TB(LF)(SN)?","answer":"It is a single-row, 3-position header with all positions loaded.
