(7)
Total bulk nonceramic capacitors on the output bus with ESR of
≥ 15m to ≤ 30m requires an additional ≥ 200 F 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) (use Type A capacitors in addition to Type B or C)
b. Type B = (1,000 < capacitance × ESR
≤ 5,000)
c. Type C = (5,000 < capacitance × ESR
≤ 10,000)
(11) Maximum ceramic capacitance on the output bus is
≤ 1000 F. Any combination of the ceramic capacitor values is limited to 1000 F
for non-TurboTrans applications. The total capacitance is limited to 8000 F which includes all ceramic and non-ceramic types.
