Aluminium electrolytic capacitors handle high ripple currents

Panasonic Automotive & Industrial Systems Europe has released two series of aluminium electrolytic capacitors to meet the market demands for higher ripple current handling. Developed from the proven V-TP series components, the V-TC and V-TCU series benefit from 1.2 to 1.5 times higher ripple current capabilities at 125°C (V-TC series 300mA for D8 can size up to 750mA for G can size and V-TCU series 400mA for F can size up to 750mA for G can size).

In addition, V-TCU parts also offer 1.2 to 2.2 times larger capacitance values (220 to 680µF) while downsizing by one can size (G to F size or F to D8 size).

Suited for applications such as automotive ECU in DC/DC filtering and output ripple smoothing, the can-shape surface-mount capacitors feature a footprint from 6.3x7.7mm up to 10x10.2mm and a lifetime of 2,000 hours for smaller can sizes and 3,000 hours for larger can sizes.

Stefan Fritsch, Panasonic, commented: “With the new V-TC and V-TCU aluminium electrolytic capacitors our customers benefit from the high ripple current and capacitance capabilities while maintaining the same land pattern as before.”
