rf inductor moulded type msc15 series the sigma msc15 is a fully moulded sister to the well known sc10 and sc15 series. the characteristics, tolerance, q, srf and dc resistance mirror almost the sc10/sc15. 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 m m m m m h colour banded coding 5% selection tol. possible log no fo624 issue 2 3-pages 02-00 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
