Electrolytic capacitors offer enhanced ripple current
Two new series of high-performance electrolytic capacitors manufactured by Panasonic are in stock at RS Components. Offering excellent characteristics for a wide variety of applications, the V-TC and V-TCU series of aluminium electrolytic capacitors are specialised miniaturised components offering ripple current and high capacitance.
The V-TC and V-TCU series are based on the proven V-TP series from Panasonic, but benefit from 1.2 to 1.5 times higher ripple current capabilities at +125°C.
In addition, the V-TCU parts also offer 1.2 to 2.2 times larger capacitance values, ranging from 220 up to 680µF, while also downsizing by one aluminium-can size, for example from G to F size or from F to D8.
The surface-mount capacitors feature a footprint ranging from 6.3 x 7.7mm up to 10 x 10.2mm, and typical lifetimes of 2000 hours for smaller can sizes and 3000 hours for larger devices.
The HL series electric double layer capacitors (EDLC) are radial components that come in a variety of capacitances ranging from 2.5F to 100F.
The components are ideal for applications that require large discharge currents including backup power supplies for servers and storage devices, auxiliary power supplies for solar-powered products such as street lighting, and driver-assist applications for actuators in a variety of markets.
The HL series capacitors offer low resistance combined with guaranteed long life over a wide temperature range from –40°C to +65°C. They are wound radial-lead devices, which can achieve far greater capacitance compared to aluminium electrolytic capacitors – by a factor of up to 1000 times more.
They also deliver superior charge/discharge performance compared with secondary batteries, offering rapid charge and discharge over more than 500,000 cycles, as well as offering exceptional ageing characteristics leading to lifetimes of over a decade.
