Astrodyne TDI 056 Feed-Through Filters & Capacitors

Astrodyne TDI 056 Feed-Through Filters and Capacitors offer high-performance Electromagnetic Interference (EMI) suppression across a broad frequency range. These filters and capacitors are designed with a compact feed-through form factor, multiple current ratings, and robust mounting options. The 056 feed-through filters and capacitors support operation up to 2000VDC or 500VAC with low insertion loss and excellent attenuation characteristics. These filters and capacitors are fully agency-approved and available in a variety of terminations. The 056 filters and capacitors are ideal for demanding environments where superior noise reduction is critical to system performance and compliance. Typical applications include shielded facilities, base stations, MRI systems, MRI gradient amplifiers, and telecommunications systems.
