New aluminium capacitors increase vibration resistance - to 50g

Five new series of aluminium capacitors, delivering increased vibration capabilities over standard devices, have been announced by Vishay. Providing high stability and reliability in automotive and industrial applications, the surface-mount 260 CLA-V, 246 CTI-V, and 250 CRZ-V, and radial 246 RTI-V and 250 RMI-V series, combine high-vibration performance with low impedance, high ripple current, and long useful life. The SMD and radial devices offer vibration resistance up to 30g and 50g, respectively. These AEC-Q200-qualified capacitors feature low impedance down to 18mohm at 100kHz for better filtering, high ripple current to 3,500mA, and long useful life to 10,000h. The devices feature capacitance from 150µF to 10,000µF over voltages from 6.3V to 100V. 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 aluminium case with pressure relief - insulated with a blue PET sleeve. All the devices are charge- and discharge-proof, so there is no peak current limitation. Polarized aluminium electrolytic capacitors with non-solid, self-healing electrolytes, the RoHS-compliant devices are ideal for smoothing, filtering, and buffering in SMPS and DC/DC power supplies, says the company.
