NOTES
1. 20MHz bandwidth. An external 2.2µf ceramic
capacitor is recommended to be placed from +V out
to -V out.
2. Requires a 2.2µf, 100V film capacitor connected
between +V in and -V in to meet FCC class A and
ETS300-386-1 requirements for conducted noise.
3. All specifications are typical at nominal line, full load,
and 25°C unless otherwise noted.
4. All specifications subject to change without notice.
Mechanical dra wings are for reference only.
5. Please refer to the Technical Reference Notes for
more information.
