  • ETS-Lindgren's LTC series of filters are ideal for applications including communication lines entering or leaving shielded rooms, computer rooms, communication terminal rooms, and Sensitive Compartmental Information Facilities (SCIF).

    LTC-X640 filters have multiple circuits to handle 2, 4, 6, 8, 10 or 12 wires, and are designed for stand-alone, individual mounting. These filters may be supplied with an optional threaded conduit pipe for penetration of a shielded enclosure.
