TDK launched ultra-compact solder-type aluminum electrolytic capacitor

TDK Co., Ltd. launched the new EPCOS B43652 * series soldered aluminum electrolytic capacitor. The new series of components have the characteristics of ultra-compact size and super-large ripple current-carrying capacity, and are compatible with RoHS instructions. The designed maximum rated voltage is 450 V DC, from the capacitance range of 270 μ F to 820 μ F, there are seven rated capacities to choose from. The capacitance value is 270 μ F to 560 μ F capacitors also have different sizes, which increases the flexibility of design. According to different capacitance values, the capacitor has 25mm × 40mm to 35mm × 55mm dia × High).

The new series of capacitors comply with the AEC-Q200 standard, and have a special performance feature, that is, they have a large ripple current capacity of up to 11.28 A at 100 Hz and 85 ° C. This feature comes from the enhanced new tank bottom design, which improves the active cooling performance. In the traditional aluminum electrolytic capacitor, the safety valve is usually located at the bottom of the aluminum tank, but the new design is changed to the side of the aluminum tank. This design improvement and active cooling option can increase the ripple current capacity of the capacitor by 85%.

One of the typical applications of these high CV capacitor products is the DC support circuit of the xEV vehicle charger.
