2944666661

The 2944666661 is a Wound Bead with 44-grade material. A NiZn ferrite developed to combine a high suppression performance, from 30 to 500MHz, with a very high DC resistivity. Wire used for winding is oxygen-free high conductivity copper with 100% matte tin plating over a nickel undercoating. Bead is controlled for impedance limits only. Minimum impedance values are specified for the + marked frequencies. The 44 material wound bead is tested on the 4193A vector impedance meter.

• Minimum impedance is typically the listed impedance less 20%
• 0.25cal/g/°C Specific heat
• 3.5 to 4.5mW/cm-°C Thermal conductivity
• -55 to 125°C Operating temperature range
