Vishay Intertechnology, Inc. introduced two new series of miniature axial aluminum electrolytic capacitors. Offered in 10 compact case sizes ranging from 6.5 mm by 18 mm to 21 mm by 38 mm, the Vishay BCcomponents 125 ALS and 126 ALX series combine operating temperatures up to +125 °C with useful life up to 10,000 hours.
The axial leads and low profile of the devices released today provide designers with greater design flexibility, while their high temperature capabilities and long useful life increase reliability for demanding applications in harsh environments. As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the devices are suited for smoothing, filtering, and buffering in power supplies for automotive, industrial, and telecommunications applications.
Featuring a cylindrical aluminum case, insulated with a blue sleeve, the 125 ALS and 126 ALX series provide capacitance values from 33 µF to 18,000 µF, rated voltages from 10 V to 63 V, and high ripple current to 1860 mA. The RoHS-compliant capacitors offer charge- and discharge-proof performance and are vibration- and shock-resistant. For automatic insertion, the devices are available in taped versions for select case sizes.
