rf inductor moulded type msc30 series the sigma msc30 is a fully moulded sister to the well known sc30 series. the characteristics, tolerance, q, srf and dc resistance mirror exactly the sc30. the current carrying capacity is similar although the specification is slightly derated due to the higher measuring temperature. this fully moulded and colour banded construction provides excellent environmental protection at a surprisingly attractive price. meggitt sigma key features attractively priced fully moulded construction rugged moulded construction wide inductance r1 - 1000 h colour banded coding 2%, 5% selection tol. possible log no fo625 issue 3 4 pages 10-00 special designs welcome. components electronic meggitt axial inductors smd inductors thin film printed inductors power chokes in radial and axial style meggitt sigma sales action desk fax: (01793 611777) tel: (01793 611666) email: sales@megelec.co.uk web site: www.megelec.co.uk
