Figure 4: loW noiSe output Filter For SmSa Dual output moDel

The filter suggestions in Figure 3 and Figure 4 will further reduce the output ripple for systems requiring very low output noise.

C1 = 0.27 µF ceramic capacitor, 500 V

C2 = C4 = 6.8 µF tantalum capacitor

C3 = C5 = 0.27 µF ceramic capacitor

Single output: T1 = 15T #28 AWg winding on toroid, µi = 5000

Dual output: T2 = 10T #28 AWg winding on toroid, µi = 5000

For best results, make interconnections as short as possible.
