Vertical SMD aluminium capacitors feature long life

8 March 2006 Passive Components

Vishay Intertechnology has added the RoHS-compliant 153 CRV series to its range of vertical SMD aluminium electrolytic capacitors, which save board space.

Devices in the 153 CRV series are compatible with lead (Pb)-free soldering processes and are specified for a long useful operating life to 200 000 hours at 40°C, enabling designers to save space without sacrificing performance or reliability.

The new 153 CRV polarised aluminium electrolytic capacitors are available in case sizes with measurements ranging from 4 x 4 x 5,3 mm to 10 x 10 x 10 mm. Standard capacitance values are from 0,47 μF to 470 μF, with voltage ratings from 6,3 V to 50 V. Minimum operating useful life is 2000 to 3000 hours at 105 μC, corresponding to 200 000 or 300 000 hours at 40 μC respectively (depending on the case size).

Vishay's 153 CRV devices are charge- and discharge-proof, and are specified to withstand surge voltages up to 1,15 times rated voltage, and reverse voltages up to 1 V. A vertical SMD construction ensures minimum board space.

The 153 CRV is suitable for applications such as filtering, smoothing, buffering, and decoupling.
