Single Line AC Filter Range – Tubular

Single line AC power line filters packaged in a tubular case designed for bulkhead mounting. The construction style provides high performance filtering in a high packing density. Suitable for voltages up to 250VAC 50/60Hz, they are often utilised in military power supplies where their high current ratings and high performance are very beneficial.

Insertion Loss Performance

Asymmetric attenuation shown as measured in 50Ω system, at all loading conditions, in accordance with CISPR-17.
Performance curve meets 100dB from 2MHz to 10GHz.
