TDK offers compact snap-in aluminium electrolytic capacitors with increased ripple current capability 

TDK’s new EPCOS B43652 series of snap-in aluminium electrolytic capacitors are characterised by compact dimensions and high ripple current-carrying capacity.

The RoHScompatible capacitors are designed for a maximum rated voltage of 450V DC and cover a capacitance range from 270microAF to 820microAF with seven types. The capacitance values from 270microAF to 560microAF are offered in different dimensions, which increases design flexibility. Depending on the capacitance value, the compact dimensions are 25 x 40mm to 35 x 55mm (D x H). 

A special performance feature of the AEC-Q200 qualified devices is their high ripple current capability of up to 11.28A at 10Hz and 85 degree C. This was made possible by a new design with a reinforced bucket bottom for improved active cooling. In conventional capacitors the valve is located at the bottom of the bucket, but in the new design it is on the side. This improvement and active cooling have increased the ripple current capability by 85 per cent, claimed TDK. A typical application of these capacitors with a high CV product is the DC link circuitry of onboard chargers in xEVs. 

The main application area for the capacitors is the DC link in onboard chargers of xEVs.

TDK was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products. TDK‘s portfolio features passive components such as ceramic, aluminium electrolytic and film capacitors, as well as magnetics, high-frequency, and piezo and protection devices. The product spectrum also includes sensors and sensor systems such as temperature and pressure, magnetic and MEMS sensors. In addition, TDK provides power supplies and energy devices, magnetic heads and more.

These products are marketed under the product brands TDK, EPCOS, InvenSense, Micronas, Tronics and TDK-Lambda.
