For types with threaded stud and d ≤ 76 mm the base is not insulated. Also refer to the notes on mounting given on page 168.
B43455 / B43457 Standard – 85 °C Special designs ■ Low-inductance design ■ 2-pad solution Design for optimized connection of the capacitor to the heatsink when using base cooling. This version is available for capacitors without threaded stud and for diameters ≥ 64,3 mm (cf. I~R(B) in table “Technical data and ordering codes” and useful life graphs).
