EPCOS / TDK B43652 Snap-In Aluminum Electrolytic Capacitors

EPCOS / TDK B43652 Snap-In Aluminum Electrolytic Capacitors feature an ultra-high ripple current capability of up to 11.28A at 100Hz and +85°C. These modules are designed with a reinforced bucket bottom for improved active cooling. In conventional capacitors, the valve is on the bottom of the bucket, but in the B43652 series, the valve is on the side. The construction improvement and active cooling have increased the ripple current capability by 85%. EPCOS / TDK B43652 Snap-In Aluminum Electrolytic Capacitors offer 450VDC maximum rated voltage and cover a capacitance range of 270µF to 820µF with seven types. The capacitance values from 270µF to 560µF come in different dimensions for design flexibility. Depending on the capacitance value, dimensions range from 25mm x 40mm to 35mm x 55mm dimensions range (D x H). These ultra-compact snap-in capacitors have a +105°C maximum operating temperature.
