Aluminum electrolytic capacitors with screw terminals

EPCOS AG 

B43750, B43770

Extremely high ripple current  105 °C

Useful life

depending on ambient temperature TA, TB, TT+B under ripple current operating conditions1)

Depending on the application, interpret the graph as follows:

1. Natural cooling

Use rated current IAC,R and ambient temperature TA.

2. Cooling of base

Use rated current IAC,R (B) and temperature of capacitor base TB.

3. Cooling of terminals and base

Use rated current IAC,R (T+B) and temperature of capacitors bas TT+B.

Ensure that the temperature of the cooled terminals is lower than that of the case base.

Due to the current load capability of the contact elements, the following current limits must not be

exceeded, even if the frequency and the temperatur factors have been taken into account:

Capacitor diameter

64.3 mm

76.9 mm

91.0 mm

Capacitor base cooling

62 A

80 A

90 A

Terminal and capacitor base cooling

75 A

100 A

110 A

1) Refer to chapter "General technical information, 5.3 Calculation of useful life" on how to interpret the useful life graphs.
