MALVERN, Pa. — July 14, 2016 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced five new series of aluminum capacitors with increased vibration capabilities over standard devices. Providing high stability and reliability in automotive and industrial applications, the Vishay BCcomponents surface-mount 260 CLA-V, 246 CTI-V, and 250 CRZ-V and radial 246 RTI-V and 250 RMI-V combine their high-vibration performance with low impedance, high ripple current, and long useful life.
The SMD and radial devices released today offer vibration resistance up to 30 g and 50 g, respectively. The AEC-Q200-qualified capacitors feature low impedance down to 18 mΩ at 100 kHz for better filtering, high ripple current to 3,500 mA, and long useful life to 10,000 h. The devices feature capacitance from 150 µF to 10,000 µF over voltages from 6.3 V to 100 V.
Surface-mount 260 CLA-V, 246 CTI-V, and 250 CRZ-V capacitors are offered in 6-pin versions and increase processing flexibility by meeting the rigorous JEDEC J-STD-020 soldering guidelines for severe reflow conditions. 246 RTI-V and 250 RMI-V devices with radial leads feature a cylindrical aluminum case with pressure relief — insulated with a blue PET sleeve. All capacitors are charge- and discharge-proof, so there is no peak current limitation.
Polarized aluminum electrolytic capacitors with non-solid, self-healing electrolytes, the RoHS-compliant devices are ideally suited for smoothing, filtering, and buffering in SMPS and DC/DC power supplies.
