Vishay Releases Surface-Mount Aluminum Capacitors
Vishay Intertechnology, Inc. released what it says is the industry’s first surface-mount aluminum capacitors that combine an ultra-low impedance down to 0.035Ω for better filtering with high ripple current to 1.75A for higher reliability, while offering more process flexibility by meeting the rigorous IPC/JEDEC J-STD-020 soldering standard for severe reflow conditions.
The new 146 CTI capacitors offer the most severe reflow soldering profile available in eight case sizes, ranging from 10 by 10 by 10mm to the larger 18 by 18 by 21mm. The devices provide high-temperature performance to +125°C, impedance from 0.035 to 0.430Ω at 100 kHz and +20°C, ripple currents from 400 to 1,750mA at 100 kHz and +125°C, and a long useful life to 6,000 hours at +125°C.
As polarized aluminum electrolytic capacitors with a non-solid, self-healing electrolyte, the AEC-Q200-qualified devices are well suited for filtering, smoothing, buffering, and voltage decoupling applications. Typical end products will include automotive power trains and chassis electronics; industrial drives, automation, and equipment for renewable energy; and SMPS units.
The RoHS-compliant 146 CTI capacitors are charge- and discharge-proof, so there is no peak current limitation. For vibration-proof performance, the devices are offered in 4-pin and 6-pin versions.
Samples of the new capacitors are available on request. Production quantities will be available in November 2010, with lead times of eight to 12 weeks
