Aluminium capacitors achieve maximum impedance at 100 kHz

17 May 2006 Passive Components

Vishay has released a family of surface-mount aluminium capacitors with very low impedance, high ripple current, long useful life, and solderability under lead (Pb)-free conditions. The new 150 CRZ capacitors are also RoHS-compliant.

Well suited for filtering, smoothing, buffering, and voltage decoupling applications in lead (Pb)-free electronic circuits, they can be used in end products including automotive components, industrial controls, SMPS units, domestic appliances, and telecom equipment.

The 150 CRZ capacitors feature a very low 'Z,' or maximum impedance at 100 kHz, that is specified as low as 0,10 Ω and a high rated ripple current of 850 mA at 105°C. They have a long 3000 hours useful life at that temperature.

These polarised aluminium capacitors have non-solid electrolyte and are self-healing. Their construction makes them charge- and discharge-proof, with no peak current limitations. Three nominal case sizes are available: 0810 (8 x 8 x 10 mm), 1010 (10 x 10 x 10 mm), and 1014 (10 x 10 x 14 mm).
