Spectrum Control

Power Filters & Film Capacitors

The film capacitor and power filter product line extensive, with nearly three decades of history, and encompasses a broad range of capabilities from black box designs, build to print power filters for commercial and military applications, standard end wrap and fill capacitors, DC Link capacitors, to completely custom film modules and power assemblies.

Surface Mount Filters

API's Surface Mount Filters eliminate the need for bulky thru-hole filters and offer compact footprints for use in densely populated PCB's

Terminal Blocks

Terminal Blocks by API are designed to provide excellent EMI/RFI filtering of low voltage DC power lines and control lines.

Filter Plates

API's Filter Plates provide an EMI filtered signal line between electronic system modules and reduce risk of damage to filter elements due to thermal shock and installation.

Low Pass Filters

Low Pass Filters by API offer a low cost solution that provides effecdtive interference protection in a variety of environments.

Filtered Connectors

API's Filtered Connectors offer low ground impedance, ground plane shielding, and consistent performance all while eliminating re-radition.

Gaskets & Shielding

API's Gasket Shielding maintains shielding effectiveness across seams or gaps and is flexible and conformable with no creasing or tearing.

Film Capacitors

API's Film Capacitors encompasses a broad range of capabilities from standard end wrap and fill to completely custom film capacitors, are used in military and commercial applications, and can be manufactured in less than an inch to several feet.
