Japan’s Voluntary Control Council for Interference by Information Technology Equipment (VCCI) will start dealing with the filing of conformity verification reports on telecommunication ports conducted EMI from April 2010. This notice is about Impedance Stabilization Network (ISN) to be used for the measurement of EMI in this case. There are two types of circuits of which an ISN is made. The restriction on the use of ISN warned in this notice is going to be reflected in the VCCI Technical Requirements (V-3/2009.04) at the next revise time, which can be viewed in the Technical Requirements(V-3/2010.04) in the VCCI Website after April 1, 2010.For more information, visit VCCI.
