37-circuit 0.25 mm pitch FPC assembly
The 503320-3760 is a 37-circuit FPC cable assembly from Molex, terminated at both ends with the housing and contacts integrated into the ribbon. The 0.25 mm pitch and 37 circuits place this assembly in the fine-pitch FPC segment, where the bend radius and actuator alignment during insertion determine the yield.
Pitch and circuit count drive the fit
The 0.25 mm pitch and 37 circuits define the board footprint — the mating FPC connector must match both the pitch and the circuit count exactly, and the contact side orientation must align with the assembly's termination.
