EMC Filters with Extremely Low Leakage Current

TDK Corporation presents a new series of EPCOS EMC filters. The B84142A*166 series of 2-line filters features types designed for rated currents of 10 A, 16 A, and 30 A at a rated voltage of 250 V AC (50/60 Hz). A particular feature is their very compact size: The 10 A and 16 A types measure only 84.5 mm x 52 mm x 38 mm, and the 30 A version only 130 mm x 84 mm x 69 mm. This permits mounting even when space is very limited. Another feature of the new series is its extremely low leakage current of less than 0.5 mA and 1.8 mA, depending on type. This prevents unintentional tripping of ground fault circuit interrupters (also known as residual current devices). In addition to their compact size, these filters offer a very high insertion loss of up to more than 100 dB.

The new filters meet the requirements for climate category 25/100/21, IEC 60068 1 and protection class IP00. The filters can be operated without derating at ambient temperatures of up to 50°C. Approvals to EN, UL and CSA are pending. Applications for the new EMC filters include converters and power electronics systems.

Main applications: Converters and power electronics systems

Main features:

• Very compact case size
