0.25mm Pitch Easy-On Bottom-Contact FPC Connectors Molex 503320 Series 0.25mm Pitch Easy-On™ Flexible Printed Circuits (FPC) Connectors are designed with a higher housing area to provide greater space savings and flexibility for applications with tight space restraints. The higher housing area enables components such as small resistors, capacitors, and selected connectors to be placed under the FPC, resulting in increased PCB space, greater cable retention reliability, and better protection of FPC cable pads.
