Product Specification
Equivalent Circuit Model Description
The DTC Equivalent Circuit Model includes all
parasitic elements and is accurate in both series
and shunt configurations, reflecting physical circuit
behavior accurately and providing very close
correlation to measured data. It can easily be used
in circuit simulation programs.
