Vishay Intertechnology has extended the voltage range for its automotive-grade 146 CTI and 160 CLA series of surface-mount aluminum capacitors to 100V and 80V, respectively. Aimed at high-temperature automotive and industrial applications, the Vishay BCcomponents devices claim to offer low impedance, high ripple current and long useful life, the company indicated.

The 146 CTI series capacitors are available in nine case sizes with operating temperatures to 125°C, while the 160 CLA series is offered in six case sizes and provides high-temperature operation to 150°C. The AEC-Q200-qualified devices feature low impedance down to 35mΩ at 100kHz for better filtering, a high rated ripple current to 1750mA, and long useful life to 6000h for high reliability.

Automotive-grade capacitors

For increased processing flexibility, the RoHS-compliant capacitors meet the rigorous JEDEC J-STD-020 soldering guidelines for severe reflow conditions.146 CTI and 160 CLA series devices are charge- and discharge-proof, so there is no peak current limitation, and are offered in 4-pin and 6-pin versions for vibration-proof performance.

Polarised aluminum electrolytic capacitors with non-solid, self-healing electrolytes, the devices are ideally suited for smoothing, filtering and buffering applications. Typical end products will include automotive power trains and chassis electronics; industrial drives, automation, and equipment for renewable energy; telecom equipment; and SMPS units. Samples and production quantities of the extended capacitors are available with lead times of six to 12 weeks for large orders.
