The 0.130\" (3.30mm) height above board makes it suitable for tight stacking applications. ## Fit and Key Specs The 0.50mm pitch drives the board footprint — tight enough for routing density but standard for this class of FPC connector. The 3.30mm stack height is the z-height budget you need to clear under the mating FPC or another board. The gold finish on the contacts is a signal-grade plating, not power-grade — this connector is for signal lines, not bus-level current. ## RoHS and Lead-Free Status The \"(LF)(SN)\" suffix in the order code indicates the part is lead-free and RoHS compliant. The \"(N)\" denotes a halogen-free version. This is a standard compliance requirement for electronics sold into the EU and many other markets.","metaTitle":"JST 40RF-JMCS-G-1-TF(N)(LF)(SN) 40-Pos 0.5mm FPC Receptacle","metaDescription":"JST JMC series 40-position 0.50mm pitch FPC receptacle, gold-plated contacts, SMT, 3.30mm height.
