Notes
1. 20MHz bandwidth. An external 2.2mf ceramic capacitor is recommended to be placed from +V out to -V out. 2. Requires a 2.2mf, 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 25C unless otherwise noted. 4. All specifications subject to change without notice. Mechanical drawings are for reference only. 5. Please refer to the Technical Reference Notes for more information. 6. Warranty: 1 yr
