The JST 40RF-JMCS-G-1-TF(N)(LF)(SN) is a 40-position, 0.020" (0.50mm) pitch FPC connector from the JMC series. 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.
