  • TDKInductor
  • The B82559 series (ERU25) from TDK is a series of helically wound SMD high-current chokes with current capabilities of up to 71A. The ERU25 is based on improved ferrite cores and the flat rectangular wires that allow a copper filling factor of almost 100 percent.

    The low core losses and compact terminal areas of the self-supporting winding mean an excellent energy storage density. Despite its high performance, these chokes have a footprint of only 23.5 x 25.3mm2 and insertion heights that vary between 8.95 and 12.85mm.

    The inductance values cover the range from 0.44 to 10 uH, and its permissible rated currents are between 24 and 71A for series resistances of 0.2 to 2.2 mohm.

  • One of the most important environmental conditions for the smooth operation of electrical equipment is a reliable quality of supply networks. In view of the increasing network pollution and the necessary reduction to comply with the power network stability, the requirements are to be adapted to device manufacturers to comply with the electromagnetic compatibility.

    As from April 2016 the harmonization of the EU Directive 2004/108/EC towards the new version of the 2014/30/EG will be effective. In order to meet these future requirements on the grid-connected emissions, HAHN already provides an extended mains choke series, which allows you within very short time to optimize the EMC-features of your device, compliant to the new standard specifications.

    With a power range up to 10A as well as a wide range of inductance values, this series covers completely the range of common household appliances using their typical plug connected load. Through compliance with the standards in relation to the relevant standards EN 61558-2-20 for chokes, EN 62041, as well as the compliance with the glow wire tests of all materials used in accordance with EN 60335-1 and the use of insulation to the insulation class B and F UL 1446, the integration of these components is quick and easy.


    Features
    •  Excellent temperature fluctuation resistance properties
    •  High electrical safety and long service-life features
    •  High voltage resistance to core
