Total bulk nonceramic capacitors on the output bus with ESR of
≥ 15m to ≤ 30m requires an additional ≥ 200 mF of ceramic
capacitor.
(8)
Aluminum Electrolytic capacitor not recommended for the TurboTrans due to higher ESR × capacitance products. Aluminum and higher
ESR capacitors can be used in conjunction with lower ESR capacitance.
(9)
N/R – Not recommended. The voltage rating does not meet the minimum operating limits.
(10) Required capacitors with TurboTrans. See the TransTrans Application information for Capacitor Selection
Capacitor Type Groups by ESR (Equivalent Series Resistance) :
(a) Type A = (100 < capacitance × ESR
≤ 1000)
(b) Type B = (1,000 < capacitance × ESR
≤ 5,000)
(c) Type C = (5,000 < capacitance × ESR
≤ 10,000)
(11) The voltage rating of this capacitor only allows it to be used for output voltage that is equal to or less than 80% of the working voltage.
(12) Maximum ceramic capacitance on the output bus is
≤ tbd mF. Any combination of the ceramic capacitor values is limited to tbd mF for
non-TurboTrans applications. The total capacitance is limited to tbd mF which includes all ceramic and non-ceramic types.
