Capacitor Supplier Verification
Please verify availability of capacitors identified in this table. Capacitor suppliers may recommend alternative part numbers because of
limited availability or obsolete products. In some instances, the capacitor product life cycle may be in decline and have short-term
consideration for obsolescence.
RoHS, Lead-free and Material Details
See the capacitor suppliers regarding material composition, RoHS status, lead-free status, and manufacturing process requirements.
Component designators or part number deviations can occur when material composition or soldering requirements are updated.
(2)
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 = (5,001 < capacitance × ESR
≤ 10,000)
(3)
Total bulk nonceramic capacitors on the output bus with ESR of
≥ 15m to ≤ 30m requires an additional ≥ 200
F of ceramic
capacitor.
(4)
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.
(5)
Output bulk capacitor's maximum ESR is
≥ 30 m. Additional ceramic capacitance of ≥ 200
F is required.
(6)
The minimum capactiance on the input bus can be less than 1000
F when using this type of capacitor. Insure that the minimum rms
ripple current rating is met.
(7)
N/R – Not recommended. The voltage rating does not meet the minimum operating limits.
(8)
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.
