EMI Filter Power Plate
3.96mm Pitch Bolt-in EMI Filter Series
EMI Filtering for High-Current Power Interfaces
Spectrum Control Filter Power Plates provide drop-in EMI suppression for high-current power interfaces, integrating feedthrough filtering into a rugged bulkhead design.
Compatible with industry-standard 3.96 mm (.156") pitch power connectors, they reduce conducted emissions without system redesigns.
High-current, compact power plates deliver connector-level EMI filtering for high-reliability applications, with patented coining on larger sizes for enhanced mechanical stability.
