Similar to LFPCN41196 issued last year in which Littelfuse migrated DO-214AB package from single strip design to matrix lead frame design ( Automation Structure ), This PCN is to upgrade another package DO-214AC to be matrix lead-frame design.

This new matrix design in DO-214AC packages will allow Littelfuse to align the same matrix structure design using among full DO-214AC series products, existing DO-214AA as well as DO-214AB products.

The matrix lead frame structure design will contribute great improvement in terms of automation, quality, productivity increasing as well as capacity expansion
