Applications
The switching transient, general application filters (STG series) have significantly better low frequency performance than the SPGA series. These filters are designed to provide greater reduction of conducted interference to meet acceptable limits of both FCC and VDE specifications with greater margins and, in some cases, may replace the STE series’ performance at less expense.
The switching transient general application filters meet the leak- age requirements of VDE and SEV portable equipment and IEC 2601 (120-volt) nonpatient medical equiptment.
