This page summarizes the board-to-FPC / narrow-pitch connectors. On this page, you can choose the best connector for use, size and current rating. Feel free to contact us for technical questions.
Please choose the connector type that suits your needs from the following connector types. By selecting a connector type, this allows you to compare connector specs by type.
Standard Type Select Map
Select map of standard type connectors.
Step 1: Select the desired connector pitch/stacking height combination from the table below. The number of applicable connectors is shown.
Step 2: For series with multiple pitch/stacking height combinations, compare specs and choose the connector that is closest to your needs.
