The 0.020\" (0.50mm) pitch means the contact centers are tight — expect a narrow footprint that routes well with fine trace geometries, but the 0.130\" (3.30mm) height above board gives enough clearance for passives under the mated pair. ## Pitch, Positions, and What the Gold Means At 0.50mm pitch and 50 circuits, this is a high-density interconnect. The gold contact finish is the right call here: tin would gall and wear after a few dozen cycles, but gold handles the hundreds of mates a test header or a field-swappable module sees. Surface-mount termination with solder retention means the part stays put through the reflow oven without tombstoning, and the tabs give the pads a mechanical anchor against the peel forces from an FPC being inserted and removed.","metaTitle":"JST 50RF-JMCS-G-1-TF(N)(LF)(SN) 50-Position 0.50mm Pitch","metaDescription":"JST JMC series 50RF-JMCS-G-1-TF(N)(LF)(SN) receptacle, 50 positions, 0.50mm pitch, dual-row, gold contacts, SMT with solder retention.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Board-to-Board Connectors"],"specifications":{"Pitch":"0.020\\\" (0.50mm)","Series":"JMC","Features":"Solder Retention","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Part Status":"Obsolete","Manufacturer":"JST Sales America Inc.","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Center Strip Contacts","Contact Finish":"Gold","Number of Rows":"2","lifecycle_stage":"unknown","Height Above Board":"0.130\\\" (3.30mm)","Base Product Number":"50RF-JMC","Number of Positions":"50","Mated Stacking Heights":"-","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8c653c81397fb0c79388c30e672d0c7e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of 50RF-JMCS-G-1-TF(N)(LF)(SN)?","answer":"The pitch is 0.020\" (0.50mm), which is the standard fine pitch for the JMC series and drives the board footprint density."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/jst/50RF-JMCS-G-1-TF~1N~2~1LF~2~1SN~2","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/jst/50RF-JMCS-G-1-TF~1N~2~1LF~2~1SN~2 when reusing this data.
