(8) In addition to the required input electrolytic capacitance, ≥ 22 µ F of ceramic capacitance is recommended to reduce the high-frequency
reflected ripple current.
(9) Required capacitors with TurboTrans. See the TurboTrans Application information for Capacitor Selection
Capacitor Types:
a. Type B = (1,000 < capacitance × ESR ≤ 5,000)
b. Type C = (5,000 < capacitance × ESR ≤ 10,000)
(10) N/R – Not recommended. The voltage rating does not meet the minimum operating limits.
(11) Total bulk nonceramic capacitors on the output bus with ESR of ≥ 15m Ω to ≤ 30m Ω requires an additional ≥ 200 µ F of ceramic
capacitance.
