Single and three phase EMC filters from TDK

TDK-Lambda has launched the R series of low profile, single and three phase EMC line filters.

The devices enable designers to combat potentially noisy disturbances in end system applications, such as those found in medical, industrial, test & measurement and comms equipment.

A choice of single stage or two stage filters is available to provide standard or very high noise attenuation levels, from 150kHz up to 30MHz. In addition, high pulse attenuation is available on some models to prevent line spikes from entering or leaving oem equipment.

The current ratings for the single phase RS units range from 0.5A up to 300A, with line voltages up to 250Vac or 250Vdc and leakage currents of 1mA.

Low leakage models are available with 10µA of leakage current at 250Vac, 60Hz. The three phase RT series filters offer current ratings from 6 to 1000A, with line voltages up to 500Vac or 500Vdc. The maximum leakage current is 2.5mA at 250Vac, 60Hz or 5mA at 500Vac, 60Hz.

For ease of installation, many of the models can be specified with wire leads, lug terminals or captive screw terminals. A choice of either standard chassis or DIN Rail mounting is also available on many filter models rated up to 30A (with screw terminals).
