Using an EMI Filter Module

Many applications place an EMI filter module in the power

path to prevent switching noise of the module from being

injected back onto the power supply. A typical application

using the Lucent FLTR100V10 filter module is shown in

Figure 14. When using a filter, a capacitor (C6) is required

noise from momentarily disabling the module.
