Vishay Releases Industry’s First Surface-Mount Aluminum Capacitors to Combine Low Impedance Down to 0.035 Ω With High Ripple Current to 1.75 A, While Meeting IPC/JEDEC J-STD-020 Soldering Standard
MALVERN, PENNSYLVANIA — Sept. 16, 2010 — Vishay Intertechnology, Inc. (NYSE: VSH) today released the industry’s first surface-mount aluminum capacitors that combine an ultra-low impedance down to 0.035 Ω for better filtering with high ripple current to 1.75 A 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 mm by 10 mm by 10 mm to the larger 18 mm by 18 mm by 21 mm. The devices released today provide high-temperature performance to +125°C, impedance from 0.035 Ω to 0.430 Ω at 100 kHz and +20°C, ripple currents from 400 mA to 1,750 mA 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 ideally 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.
|Case sizes (mm)||10x10x10 to 18x18x21|
|Capacitance at 100 Hz (µF)||22 to 4,700|
|Voltage range (V)||16 to 63|
|Impedance (Z) at 100 kHz, 20 °C (Ω)||0.035 to 0.430|
|Ripple current at 100 kHz, 125 °C (mA)||400 to 1,750|
|Temperature range||- 55°C to +125°C|
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.
