Notes:

1. 20 mHz bandwidth. External 10 uF tant. capacitor +

0.1 uF cer. capacitor placed from +V out to -Vout.

2. Requires a 2.2 mf, 100V film capacitor connected

between +V in and -V in to meet FCC class A and

ETS300-386-1 requirements for conducted noise.

Consult Factory for filtering information to meet FCC

class B, VDE or EIC specifications.

3. Suffix -”6” for 3.7mm nominal pin length, “T” for tuned

version for specific transient response requirement.

Minimum output capacitance required. Refer to

Technical refernce Notes for details.

4. All specifications are typical at nominal line, full load,

and 25°C unless otherwise noted.

5. All specifications subject to change without notice.

Mechanical drawings are for reference only
