(7)

Total bulk nonceramic capacitors on the output bus with ESR of

≥ 15mΩ to ≤ 30mΩ requires an additional ≥ 200 µF 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 µF. Any combination of the ceramic capacitor values is limited to 1000 µF

for non-TurboTrans applications. The total capacitance is limited to 8000 µF which includes all ceramic and non-ceramic types.
