Com-Power LIT-153A Transient Limiter
Frequency Range: 150 kHz - 30 MHz
Transient Limiter helps limit the transients when conducted EMI emissions measured using Line Impedance Stabilisation Network (LISN). The EMC receiver input is connected live and neutral line of the product via the LISN. The LISN blocks the supply voltage from LISN RF port but allow the RF signal to pass without much attenuation, so that it can be measured with a EMC receiver. Because the RF signal must be passed through, any short transients (a few microseconds or less) on the power supply lines will also be passed through.
