Vishay’s Capacitors Achieve Max Impedance at 100 kHz

Vishay Intertechnology, Inc. has added a family of surface-mount aluminum capacitors with low impedance, high ripple current, long life, and solderability under lead-free conditions. The new 150 CRZ capacitors are also compliant with the European Union's Restriction of Hazardous Substances (RoHS).

Designed for filtering, smoothing, buffering, and voltage decoupling applications in lead-free electronic circuits, the new capacitors can be utilized in end products including automotive components, industrial controls, switch-mode power supplies, domestic appliances, and telecommunications equipment. The 150 CRZ capacitors feature a low "Z," or maximum impedance at 100 kHz, that is specified as low as 0.10 ohms and a ripple current rating of 850 mA at 105 °C. They have a useful life of 3,000 hours at that temperature.

These polarized aluminum 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 mm x 8 mm x 10 mm), 1010 (10 mm x 10 mm x 10 mm), and 1014 (10 mm x 10 mm x 14 mm). The surface-mount design with base plate is reflow-solderable in accordance with their datasheet.

The new 150 CRZ capacitors are supplied in blister tape-on-reel packaging. Samples are available now with lead times of four to seven weeks, and production quantities are with lead times of 8 to 12 weeks for larger orders.
