Tantalum SMD Chip Capacitors Have Undertab Terminations

AVX Corp. has released a series of fused high CV tantalum SMD chip capacitors with undertab terminations. The F98-AS1 Series capacitors feature a proprietary lead-frame-less structure with precise dimensions and low stress packaging, an internal thin film fuse that protects against short circuits, and well-established undertab termination technology, which enables high volumetric efficiency and high PCB assembly density. Currently available in a 0805 (2012 metric) S case with four ratings (22 µF/10 V, 33 µF/10 V, 10 µF/16 V, and 1 µF/35 V) and a 0.9 mm maximum height, the F98-AS1 Series is the smallest and thinnest SMD fused tantalum product currently available on the market. As such, the series is ideal for use in a wide variety of applications in which safety and size are a primary concern, including: automotive, commercial, industrial, and medical applications, and the input/output lines of small power supply circuits, portable gaming devices, and smartphones.

F98-AS1 Series capacitors are rated at 85 °C and designed for use in temperatures spanning -55 °C to +125 °C. The series is also lead-free compatible and RoHS compliant.

Series extensions currently in development include a 0805 (2012 metric) case 47 µF/10 V capacitor and 10 capacitors packaged in 0603 (1608 metric) M cases: a 1 µF/25 V component, a 1 µF/20 V component, 10 V components rated for 2.2 µF, 4.7 µF, 10 µF, 22 µF, and 33 ÉF, and 16 V components rated for 1 µF, 2.2 µF, and 4.7 µF.
