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.
