TDL-MICAP^®high voltage/high temperature reconstituted mica capacitors are also available in other styles.

DXTstyle are housed in G10 fiberglass cases and vacuum encapsulated with selected epoxy, polyurethane, or silicone resins. A wide variety of terminations and mountings (inserts, studs, turrets, insulated wire, flanges, etc.) can be incorporated into this style.

DSSstyle are housed in heliarc welded stainless steel for use in extreme environments such as 200C temperatures, strong electromagnetic fields, or severe shock and vibration applications.

TDL-MICAP^®capacitors are manufactured in a modern facility using advanced state-of-the-art Computer Aided Designs, efficient production methods and rigid Quality Control. These capacitors are in wide use on many airborne, shipboard, and ground-based radar and jammer systems in both the power supplies and the transmitter. Our engineering staff has the experience necessary to create unique solutions to your most demanding applications.
